View Full Version : Problem with Dell GX280

I think I have a heating issue with my Dell GX280 system (at work). Whenever I use a "big" application (like Adobe), this thing starts screaming (fans run at full speed I guess) and I can feel the heat waves coming out of it. The air flow is very fast in the back of the case. Tried checking temperatures in BIOS, they don't have that facility in the BIOS.

This is the system cofig:

Pentium 4 3.4GHz (560)
1GB DDR 400 Dual Channel
Radeon X300 256MB
160GB SATA HDD

The system never freezes, nothing strange happens, just the "lawn mover" noise everytime I do something serious with it.

Can somebody guess what's goiong on? This has 3 year on-site warranty. When I contacted "award winning" tech support, they asked me to take the system apart and test what fan makes the noise :mad: My guess is that this is either a BIOS or motherboard problem.

Sounds fake because there's no reason why Dell wouldn't set up service (or that it would take you more than 60 seconds to look at both fans), but i'll try to "help" you anyways.

There are only 2 fans in the case: one in the PSU and near the heatsink. The heatsink fan is in the back of the case on the ATX case and near the front on the BTX case. The P4 3.4GHz (P4 550, not 560 as you posted) is only an 84W processor, so its doubtful that you "feel the heat waves coming out of it", especially if "air flow is very fast in the back of the case."

The two things are exclusive. If the fan was running slowly under a heavy load, it's possible that the exhaust air would be very hot. If it's a light load like "Adobe" and the fan is blowing fast, the air will be cool.

Even when encoding (100% on both logical processors), my GX280 with P4 551 and 6600GT only has a moderate exhaust temperature and the fan blows at a medium speed, still pretty quiet. Even with gaming, the system doesn't run hot.

If you think this is a fake, please don't bother to offer help. I've had very bad experiences with Dell. However, I have no choice at work but to go for a Dell. If you work for Dell.. thanks for the "help".

Here is part of their e-mail to my query (I deleted names in this):

Is this the mini tower/desktop? We have the same problem with ours, Dell kinda just tells us to deal with it. For us, its the processor fan that fire up super loud. Blame the Prescott I guess :confused:

I kinda doubt its a fan. Im thinking ur HD is going bad. had that prob with a Dell Optiplex years ago. Open the case and target where the noise is coming from. In those computers the fans will not change speed when you operate large programs but the rotation of the HD will.

I feel you on the Dell situation. Their tech support is a joke unless you buy 10394308 computers from them.

Processor fan could be the issue but im leanig toward the HD. Open the case and find the noise.

vsrdan
07-10-2005, 06:58 PM
I guess so, too. Processor fan is connected to a duct which exhausts hot air directly to outside (that's where I feel hot when it is screaming loud). I don't think changing a fan would do any good.. this is a more seriuous issue.

I am really scared to use this system for any work (analyzing and storing research data - main stuff I am supposed do with this). For me, this thing is pretty useless. We have low-end older Dells (P-II's and P-4's) at work, and they are working fine.

HDD is working OK, but I'll give it a try tomorrow when I go to work. But I really think it is the CPU fan which makes the noise and CPU overheats. Thanks for comments/suggestions!

Have you ever called Dell support? Hours on the phone listening to music and at the end to talk to somebody who doesn't even understand English. I have more important stuff to do at work.

I just posted this one problem to seek any helpful hints from others to get this piece of junk back to work without wasting my time.

If you are interested in I have more interesting stuff about Dell (related to purcheses I made both at work and for personal use) - there is no point talking about those right now. One good thing Dell did, I should appreciate, was that they made me a system builder.

Everyday innocent unsuspecting people getting into trouble after purchasing this kind of computers. If you love Dell, that's not my problem. However, you have no right to label people "liars" and try to save Dell's #@s when you don't know facts.

So you didn't try calling in? You won't have to wait "hours". The last couple of times I called in to small business support, it took 5-10 minutes to reach a tech. Dell's business support is in the US. http://www.msnbc.msn.com/id/4853511/

All i'm saying is that in the time you've been messing around with the problem, you could have had service set up and your problem solved already. But if you prefer to complain and go through email support, more power to you. :rolleyes:

if you have free onsite service, and its unlimited for so many years, use it by all means. A professional will come out and determin what's up. He might even have a little laser temp sensor to see how hot the heat sink is getting to see if its "overheating". Sometimes these people do not work for dell, but a smaller computer service business.
I had the pleasure of seeing one of my lousey roomates get his laptop taken apart by a guy, and he knew what he was talking about.

Is the hot air comming out of both the case and the PSU? The PSU might have the only variable speed fan in your system, though i have no idea.

When you do get to work, and determin what exactly is making the sound, ide love to know.

Again, call support, or have someone above you in IT do it for you(if this applies to you, which i will assume it does, because you were "forced" into getting dells).

I have had so many issues with this system. This is the most serious one I have right now. IT/Computing guys in the Dept. don't know how to fix this. They know as much as I know :) about this thing. Also, I cannot ask people above me bacuse they already wasted lot of time (hours talking to many people at Dell) for me on this system when Dell replaced the brand new (and faulty) LCD monitor with a refurbished one (dead pixels and other issues) just after 20 days of use (we paid for a brand new monitor and almost ended up getting a piece from their junk yard). I don't want to continuously bother others in the Dept. to fix this one faulty system. That's the real reason for me to post this (original) question here.

I guess I am going to e-mail Dell one more time and see what they'd do. I am done talking to them over the phone - since long time ago.

Once they sell a piece of junk to you, all the problems come with that thing is yours (that's their customer service).

ever tried their dell support through online chat? that way if they give you an answer that is not acceptable, you can tell them right away, whereas e-mail may take 2-3 days for a turn around.

Anyway, I bet your company or place of employment got a "good deal" on the dells. Good deals usually mean non-american jobs were used for cheaper labor costs.(if your not in america, sorry this sounds very biased)
I wish more US companies would purchase products that support people working in the US. http://www.aquaria.info/modules/PNphpBB2/images/smiles/crybaby2.gif

Since this thread is heading somewhere else without solving my computer problem.. here are some info that might be useful. My workplace is a state govt. institute. My job is in scientific research. I use this computer to record, analyze data, and compile reports/presentations, etc. That's why this is so important to me. By the way, I am in the USA.

Mr. pxc says he was using Dell's for several years (in another thread regarding a crashed dual Xeon system) without a single problem. I've been using Dells since 1996 (in two other countries and in the USA). We don't have to waste time talking about the past. I wanted some good advise to fix the CURRENT PROBLEM WITH THIS GX280 I have at work. I don't do paperwork at my work. Almost everything is handled through computers. Try to understand the situation when you have a computer which is about to crash anytime at a workplace like that :( That's my problem. I didn't mean to start a fight with Dell spporters here.. I just wanted to fix the problem I have. So, if anybody have anymore advises (I could try this week), I really appreciate those. Thanks all for comments so far! :)

I would say run a disk check for sure...then look into replacing your CPU fan. Also, if there are any other slots for fans that are unfilled, fill them. I reckon that dell would use the cheapest fans possible, so replacing their stock with something quality might make a difference. Otherwise, just try running the thing with big apps till it burns to the ground, and then get a replacement under your warranty...

We use Dell GX270s at work, There 3.0Ghz CPUs. The fan on the back of the case is a 92x38mm Nidec DC fan (Product link (http://www.nidec.com/ta350dc38/ta350dc38.htm) ) the one the gx270s use is a M34859, witch if you look at the link you will see is 110CMF max at 50DBA!!!!

The fan is on a thermal sensor, so questions: Look at the fan, find the sensor, is it damaged? if its not that ill just bet its a combination of you 3.4Ghz CPU (one hot mofo!) and the location of the computer? Is it hot where it is? Because the fan is desinged to get faster as it get hotter. Assumming the sensor is not dammaged im sure it jsut getting lud because it overheating?? What do you expect it a 3.4Ghz intel chip.

thats still hot as shit, my GX270 with a 3.0Ghz Prescott runs hot as hell, when the comptuer was under my desk It would rev that fan full blast at least 2 times a day. When i moved it to on top my desk It has not done it since. (I do have 3 computers under my desk at work so its a tad hot down there)

The Dell BIOS dose not controll the fan im only outputs 12v and monitors the RPM. the fan is controller soly by the thermal DIOTE o nthe fan itself, so its not the mobo or the BIOS doing it..

Ok, sounds like the thermistor on the fan is bad. I've had a couple of them in my territory that'd do the same thing. Call tech support, tell them you need a new CPU fan and they should be able to send out a tech on the next business day. If you work for a Gov't agency, odds are you have Gold tech support. You'll be on hold 5 minutes tops and get somebody in TX or GA. I can swap em out in under 10 minutes.

It seriusly may still be a good fan, and jsut need to be that hot. Dell has a shitty ass "non-direct" CPU fan it pulls air thru a non so air tite duct. The CPU fan is the exaust fan, so if its gettign remotly hot it may need that might air flow to pull air off the CPU HS.. you can call them anyway, they will send you a fan and you jsut box up your old one in the box the new one comes in..but ill bet it still dose it..

Man our next batch of workstations are going to be GX280...

Wait, I just remembered something. I had a workorder up at my school once (local community college) they had a GX280 with Socket T prescott mid-tower with the very same problem. Fan would kick into high gear all the time. I replaced the fan first, didn't do squat. I noticed the Heatsink (which is the BIGGEST freakin heatpipe I've ever seen) wasn't getting warm at all up near the fan, and was blisteringly hot at the base. The system needed a new heatsink, my guess is that the heatpipe had a pinhole leak in one of the solder joints and all the coolant escaped. So it might behoove the OP to ask for a new heatsink too.

BTW, Dell's on-site service does not cover initial troubleshooting, that's what the phone monkeys are for.

Last time it went something like this..

Me: Game my account #, name, service tag of the particular box
them: ok whats the problem
me: I need the motherboard replaced
Them: Is it bad?
me: yea, It wont post, I pulled all the parts and tried them in a diffrent box, everythign eles worked but the mobo in this box will not post, and the south bridge has got a burn mark bubble on it..
them: OK we will sent you one it will be there tommorow morning..

this was at 7:00 in the morning..the replacement motherboard arived at my work that after noon bout 4:00..

But yea if there is a chance the HS is bad too, the have them send you a new HS and rear fan...shit ask for a new CPU as well.. lol if the stuff you send back is in working order then they will just use it in another box anyway...

Light a 75W regular bulb and see if you can touch it after 5min or so. That's how hot a 75W could be.. then imagine a 85W. A CPU is not as big as a light bulb. Talking number of watts wouldn't solve this problem I have.

Can I put a .25C/W heatsink and fan on it? I'd gladly touch it then. :D

Make sure you have the "Performance" heatsink, it has more heatpipes, the insane spinning fan noise issue was common on the GX270's with the stock heatsinks..

Found this post just now in the dell forum about GX280 noise...fixed with performance heatsink...

Last time I called mine went like this (for an optiplex GX270):

Me: This system has a bad motherboard. Everytime it POSTs it give an error about a thermal event.
Them: Yeah sounds like the motherboard. I can overnight you one today. Do you want parts only?
Me: Yeah, Parts only.
Them: Okay here is your case number if you need to call back. Have a good day blah blah blah.

Has Dell's support finally gotten better? I was only on hold for 2 mins max and got somebody who spoke English as a first language. I work for an international company with sites all over the US and abroad but they never buy long warranties because we never fix machines if they are more than 2 years old or so. So I know we don't have a gold account with them or anything. I called at about 2:00 PM and the replacement board was there before 9:00AM the next day.

Contacted Dell today (by e-mail - after listening to the "music" for few minutes) to obtain a heatsink, fan, etc. to replace faulty parts. Hopefully they'll reply soon! I am pretty sure it is a defective heatsink/fan by now (did some benchmark tests to check the system today. The noise almost freaked out others in the office, but the system didn't fail).

Thanks to all who responded with all the good information :)

Will update here when I receive the parts (or something important happens).

I work for a school district and we have about 100 of the little mini GX280's in our CAD classrooms. Those fans all get super loud when under load. Luckily Dell finally moved to BTX so hopefully the new model we're buying this year isn't as nasty.

Guys this is about the heating/fan noise issue of my GX280.. not about outsourcing or Indians in Dell's tech support. I don't care whether they outsource their tech support to India or somewhere else. I was worried about the overall quality of their service offered to me for this system.

Afterall, more than 99% (corrected below) of computer hardware is made in Asia, and I know there are excellent computer techs in Asian countries (compared to most of those in Western countries).

The ONLY reason your fan isn't as loud as it was is that it's not cooling the CPU very well and is drawing cooler air from other parts of the case...The shroud is there for a reason.

Yeah, it's there for a reason, and a stupid one at that. Dell is so cheap they won't even supply a standard CPU fan... :mad: WTF!?! Instead they rely on one pathetic CASE fan to do the job of an independent CPU fan... this is another reason I hate Dell. Why skip such an important cooling device? What would a CPU fan cost a big OEM? $2? Maybe less? :mad:

Anyway, my PC has been running strong (and quiet) for over 7 months now with the shroud off, and that's in 30C+ weather. If something was to overheat, it would've cracked by now. :)

That "Case" fan that Dell puts in their systems moves more air than you think when on full blast. It's quite effective actually. Maximum PC did a sort of "wind tunnel" test of sorts in several different systems including a Dell with a fan shroud. The test involved funneling fog from a fog machine inside the PC's whilst running, it turned out the Fan shrouded Dell was one of the top performers in terms of overall cooling of critical components.

While the fan shroud might be useless to us enthusiasts who can tolerate 10 uber CFM fans. The average computer buyer won't tolerate anything noisier than their central heat/air. I've had customers complain when their PC was half as loud as my main rig. Using the fan shroud and a single thermostatically controlled fan ensures adequate cooling of the CPU whilst keeping down the noise level.

Also, removing that shroud is detrimental to the cooling in your system (unless you've added a fan) Right now there's not much airflow across your heatsink, the shroud is in place to ensure maximum airflow across the heatsink with minimal noise. It might not be causing a problem for you, but your CPU sure isn't as cool as it would be with the shroud. I've been building and repairing PCs for going on 6 years now and I've had a general interest in PC Gaming for more than 10. So trust me when I tell you that it would behoove you to replace that shroud.

I work for a school district and we have about 100 of the little mini GX280's in our CAD classrooms. Those fans all get super loud when under load. Luckily Dell finally moved to BTX so hopefully the new model we're buying this year isn't as nasty.

You got to get all the heatsinks (of loud machines) replaced by Dell. This problem is due to a defective heatsink. I am pretty sure about it by now.

Make sure you have the "Performance" heatsink, it has more heatpipes, the insane spinning fan noise issue was common on the GX270's with the stock heatsinks..

Found this post just now in the dell forum about GX280 noise...fixed with performance heatsink...

You are ABSOLUTELY RIGHT! (Thanks for the tip). Heatsink was replaced (by Dell) yesterday and the system is normal now.

The GX280 heating problem was solved thanks to this forum (not Dell customer support). Thanks to all who offered me valuble tips to resolve this issue. I am not going to thank Dell (although I like the way they responded in this case) because their technical support never understood or tried to understand the real problem (as I wrote before, they were asking me to take apart the system and look for defective fans, which was not the cause of the problem).

The best advise I received in here was extracted from Dell Community forum (which Dell is trying to close??) and seems like many others have this problem with GX280 (and most of them don't know what to do). Imagine something like this happening to an automobile manufacturer - they'll have to recall all defective vehicles and fix them for free. However, for computers, it is not the case yet. One can argue that these are not life-threatening situations (as in the case of vehicles), but a faulty computer which handles a lot of important things (like mine) can decide a lot about my/my workplace's "life" and future. Also remember, a lot of tax payer money is WASTED by state and federal governments on buying these.

Getting this thing resolved doesn't mean I am becoming a Dell fan. I still have my outstanding laptop computer case (explained in post #11 here (http://www.hardforum.com/showthread.php?t=926448) ) and bad experience on monitor deal with Dell.

My advise to others (as of now): Think twice if you are buying a Dell - specially if it is for your personal (home office) use. Basically, be ready to forget about the money you spent on your system (home) if it is broken. Also, back-up all your data at the end of each day/work if you are using a Dell for ANY important work.

Thanks again for all the comments/suggestions you all offered me. This forum is way better than Dell's "award winning tech support".
