I am gettign rather desperate. I am runnign a zalman 9500, which I have installed twice, and am currently getting no response in my thread regardign that installation, so I figured I would attack it from a different angle. Can the vanilla p5B read core 2 temps right? The board brags abvout being core 2 ready, but it seems as though I need a bios update anyway (uCode error on boot that I can dismiss, people have said a bios update fixes it). It starts at around 44C, then rises to 50C as I watch it in bios. Used as5, had a blob that the hsf aquished - should I have done it dfferently? I can move the fan a bit, like 5-10 degrees somewhat easily when i try to twist it, otherwise it does not move. A visualinspection shows the fan installed exactly as instructed, clips are definatly putting an ample amoutn of pressure on the proc.

I do not have a windows install yet, and I need to run memtest/prime95 for a total of 3 days, need to be a t a lan in 1 week, at college in 10 days, so this need to be DONE. I apologize to anyone who consioders this cross posting, but I am adressign different aspects of the same problem.
 
cpu temp is usually higher in the bios as far as i know,something about it somehow putting load on the cpu or something.once you have windows installed monitor cpu temp from there.

as for thermal paste application you want to have a thin layer spread over the cpu and then maybe put a blob in the center just before putting on the hsf.you can also try cleaning the cpu and hsf base with alcohol so there wont be impurities that hender the pastes conductivity.

to spread the paste you can use a piece of plastic or a razor or even one of those small plastic bags around your finger...........
 
forgot ,if bios is buggy defenatly flash a newer one,could also affect temp reading if there was a bug there too.
 
flashed to the latest bios, same temps. It seems to be stable after 1.5 hours of memtest, i am letting it run overnight to thoughly test the memory. Perhpas I will try the stock cooler if I fail to install this f*cker right for the third time...
 
my E6700 with zalman 9500 + AS5 gave me 43-50(c) !! with a P5B deluxe and ive reinstalled it 3 times.

A bud with a P5B DL told me Asus boards are reading 10 to 12C higher than the actual temp.
 
If you can find my thread I made a day or two ago it was about this same problem. The only program that is currently known to give accurate readings is called "core temp". Speedfan, mobo monitor, and the utilities that ship with the p5b vanilla do NOT read temps correctly.

I was having the same problem as you. Do not worry, you are probably doing everything right. Get Core Temp and be happy.
 
Are you sure about that? Core Temp 0.9.0.91 gives me the same temp as in PC Probe with my p5b Deluxe. somtimes 1 degree cooler.
 
I am having the same problem. P5B vanilla mobo with the e6300 and correctly applied arctic silver. I idle right at about 50C. I have reapplied the paste about 4-5 times (including cleaning the psu and heatsink thoroughly). So thats not the problem.
 
well my p5b deluxe and e6400 experience sucks.
Idle was 49C. stock everything
after thinking it was something I did wrong I removed everything cleaned and then lapped the cooler, and this damn ninja was anyting BUT flat.
after doing everything I can think of, 47.5C stock temp

its the same with coretemp speedfan and asus monitor, all show within 1C of each other
2 prime95 and it maxes at 59C...would not go higher

funny how more and more people are seeing super high temps on stock cpu's

just like the launch these processors are fucked as well...cool low watt....hell a preshott doesnt idle this high

That is actually a pretty normal temperature.

I am now idling at 39-42c and on load hitting no higher than 50c however averaging around 47-48c.

I've used core temp, speedfan, aisuite and probe and all get very similiar results. I am running a Scythe mine with AS5. My temps seemed to go down after my OC and a few days of letting the AS5 sink in. My ambient temperature is around 79-80f.

Download core temp at that link.

Even after priming my heatsink and heatpipes are only slightly warm not incredibly hot. Those people claiming sub 30c idle temps on air are full of crap. They must be in a meat freezer...you have to remember that no matter what the processor will produce heat. It is impossible to be below your ambient temperature with air. As long as you are not spiking above 60c on load I wouldn't be concerned. Even with my OC to 3.0ghz I'm BARELY hitting 50c and it's only for a few seconds. Average is roughly 46-48c under load.

Also note my buddy has a E6400 with a P5B vanilla and is having the same issue with temps we are running within a few degrees of each other. He is currently running at 2.51ghz.
 
Both of us are using very large heatsinks too. As I mentioned in my thread regarding heatsink installation, it seems as though some of the conroe chips shipped with concave heatspreaders, but mine clearly disturbed the AS5in all areas,so I am not so sure...

So, I should definatly not trust bios then? I have no wiondows install atm,in fact it jujst failed an 11 hour run of memtest,so I will likley be returning most of the computer anyway.

Why? You are going to have the same issues with whatever you get.

Do you see how many people are having the same issues as you and are running their computers just fine?

Just deal with the little bit hot temps. It's not that big of a deal...
 
My previous post was only directed at P5b vanilla users, not deluxe users. I can't say for sure if the information I posted is relevant to the deluxe version of the board.
 
I have an E6600 (no overclocking yet), Zalman 9500, and an Antec P180. Core Temp has me idling at 47C and it goes to 51C-53C under load. Speedfan shows me as 39C idle and 41C under load. I know this falls under the realm of "normal" but I know that I can get it lower. Would it help to have the Zalman pointed up instead of back?

Pretty much nothing make sure you have AS5 and that it is tight and you are good to go.

You could also remove your NB and SB HS and apply AS5. My buddy did that and noticed a 7-10c drop in temp.
 
50c is not a killer. Staying under 55c load you should not really have any problems either, but I wouldn't leave it like that forever.

Maybe get a thermal probe to get an accurate reading.
Try a different cooler. My Big Typhoon is great with the DS3.
E6400 clocked to 3.2 ghz 28c idle / 32c load.
 
you can also manage your cases airflow ,are there lots of intake fan but not enough exhusts....etc.

Pardon my noobishness but what is the best practice when applying thermal grease? And how do I know that I've tightened the HSF enough? Should it not be able to move at all? Currently I can pivot it a tiny bit.

For my case, there are two exhaust fans above and behind the CPU and one intake fan on the front of the case.
 
Got my memory problems fixed, installed windows. Using core temp, I am currently running idle at 43C/43C (core1/core2), and under load it shoots up to 55C/54C. Speed fan gives me only one temp, which was at 35C running dual prime95.

E6400 (stock)
Asus P5B
Zalman 9500
 
I used to have a zalman 9500 but I later found that the plate was not even and not all the AR5 was making contact between the top of the cpu and the HSF. This was on my old amd system and I returned the dang thing.

Make sure that all the AS5 paste have contact. I'm currently using the Asus Silent Square with AS5 on my E6400 and DS3 mobo. I'm running at 32C idle and 44C at load with an OC of 3.2gh. Its running fine, no problem here.

Edit : My mobo is at 42C while my cpu is at 32C at idle on 3.2 gh on my e6400

Put a fan on your NB and your MB temps will go WAY down!
 
speed fan is only reading your motherboard temperatures...

Touch the heatsink if it's really that 60C it should be warm and hot in the base... If not I wouldn't worry too much about it...
 
I have a P5B Deluxe and a E6400, and the processor's idling at 39 degrees with a load temperature of 53 degrees. This isn't anything out of the ordinary, except the heatsink fins/base are COLD during idle and are only slightly warm during full load. I reseated the heatsink (a Scythe Ninja) a few times and temps stayed the same, so I'm sure I mounted the heatsink correctly.

Because of this, I'm fairly confident that the P5B Deluxe is reading a higher temperature than the actual one.
 
Same deal here, the base of the fan is not that warm at all while idle. But soulb motherboards affect readings from core temp?

You shouldn't have any problems..

It's proabably reading the temps higher than what it is...
 
I need to know what the deal is with the temp readings on the conroes man. Everest and Coretemp has the same reading for my E6300 of on average 54 degrees idle! I have reapplied arcticsilver and reseated my zalman 9500 at least 7 times. What's the deal? Why are my temps so high at stock? Wasnt these 65nm chips to be as cool if not cooler than amd chips? My 3000+ Venice idled at 34 :( What's wrong?

Touch the heatsink fins (or base, if you can) during idle. Are they warm? If not, assuming you've seated your heatsink correctly, I wouldn't worry about it. Everest and Core Temp are probably reporting higher temperatures than what they actually are...
 
the base is warm-ish, but even with my last cpu the fins never got hot and that was with the 805 at 65 degrees. I just need an app that can correctly report the freakin temps. With the 805 and all my past cpu's, I noticed that temps were usually much higher in the bios than when windows actually starts. I assumed that was because the cpu was doing everything including graphics until windows would load the graphics drivers and take the strain from the cpu. That being said, my temps in the bios are about 45 degrees, that makes me kinda think that coretemp is reporting wrong but i just want to know for sure. This temp thing has limited my overclock, I actually went back to stock to avoid any trouble but even stock is reporting as being hot :(
 
My bios temps are around 10 degrees higher than those reported by core temp. Perhpas I will wait to buy a new heatsink and see if anyone can come up with a way that actually reads these temps correctly. I also noticed that my temperatues drop several degrees at night, so I am going to get a themometer and see how hot my room with no ventialation really is :)
 
Running P5B-D 0507 with stock HSF w/artic silver E6700 and BIOS reads 55c idle, ASUS probe reads 55c idle / 67 under load and CoreTemp reads 43-44 and 58 under load. I hate this HSF, but after reading this thread it looks like my temps are right where they should be.

Put a physical temp probe on the CPU... shouldn't be expensive... People worry way too much... None of these CPU motherboard reading are usually never accurate...

And if you're overclocking by nearly 1000mhz and adding more juice into the CPU you will get higher temps... Something like 10-15C with a good air cooler

If it's stable and pass all your stress tests what does it matter?
 
I'd check to make sure your heatsink is making good contact with the heat spreader. The easiest way to do this is to remove all thermal compound from both the HS and heat spreader, then apply a THIN coat of prussian blue to one or the other (preferably the heat spreader). Mount the Heatsink exactly as you did before, then remove. **DO NOT POWER ON WITH THE PRUSSIAN BLUE IN PLACE**
Look at the blue that transferred to the heatsink.

It's also possible (though unlikely) that your processor core is not in sufficient thermal contact with the heatspreader. I wouldn't advise trying to fix that yourself, though. Voids warrantee and alot can go wrong.
 
It's worth noting for anyone that has missed this (from arcticsilver's website):

Important Reminder:
Due to the unique shape and sizes of the particles in Arctic Silver's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

That could take from 2 to 3 weeks or more.

I don't think repeatedly reapplying the compound is the answer.
 
I'm somewhat skeptical of the temps people are reporting, I’ve installed and tested two different E6600's and both when clocked at 3400 require at least 1.45Vcore and idle around 45C and load at around 65C.. Tested using scythe ninga and also a SI-120 both with 2000rpm fans.. This is with gigabyte DS3 and DS4 btw..

The bios tends to read 30C idle and 50 load.So the bios is reporting around 15C lower then coretemp.. I don't really understand how people are getting such small differences between their idle and load temp... They really shouldnt be within 10C of each other with air cooling.. nevermind 5C difference..

Also, at full load the heatsinks are not that hot, just warmish... the chipset is much hotter to touch so I'm not sure any of these readings are accurate.. :(

I agree! Yet I haven't found two programs that give me similar temp readings. With 4 apps, I got 4 different temps and NONE of them are even close!
