After ocing my e6750 to 3.8 cpu temps seem to be fine but my northbrigde is like on fire :eek:

Is there a good nb cooler that will not interfere with my true 120 and the vid card right below it.Mobo is gigabyte ep35c-ds3r
 
I had a little extra cash laying around so I thought I'd try the Xigmatek Porter N881 NB Heatsink
http://www.xigmatek.com/product/air-portern881.php

It was $25 at newegg + $7sh.

Anyway, my original NB heatsink (Asus P5Q) and temp skyrocketed to 56C, so I thought I'd add an aftermarket NB hs. I picked the Xigmatek because it can accomodate an 80mmx15mm fan and it angled back to fit with a large CPU HSF. I also like the HDT and rubber fan mounts.

It arrived, and I went to install it removing the motherboard.

Install was a pain in the ass. I mean, it wasn't impossible, but getting the thing centered on the NB chip, securing it down, all the while holding it in place, and using tiny thumbscrews and springs, and tools... all at once. Needless to say, it was an excersize in patience and dexterity. Not only that, once installed, I removed it to check spread and to make sure the single 8mm heatpipe was centered on the die. It was, and back into the breach!

Well, when it was all in, I found one problem. There wasn't enough space between the NB heatsink and the CPU HSF to fit the 15mm thick fan. *cries* Oh well, time to see how this thing performs passively.

Plugged it all in, closed up my 690 case, and powered her on.

I measured temps after my pc was on for awhile. My temps went from 56C to 42C. Not a bad drop. I'm sure if I could have fit the fan, it would have dropped more. Perhaps I can find a 10mm thick fan somewhere.

Oringal NB hs = 56C
Xig NB hs = 42C

Looks saaaw-weeet with an 80mmx15mm fan:

Lack of fan (and I know the clip is backwards on the cpu hsf)

3.8Ghz? That must be nice. My crap-ass motherboard (MSI P6N Diamond) won't let me past 3.1Ghz no matter what I try.
 
I used thermalrights hr-05 ifx/sli. Nb hangs at 39c w/ 1.5 going through it.
I have another thermalright hr-05 sli(not the IFX version) I'm trying to get rid of if you want it PM me.
 
Just put a little 40mm fan on the northbridge heatsink and you'll be fine. You don't need an aftermarket heatsink.
 
you'll most likely have to get one w/ bent heat pipes. The thing is though it'll be next to the gpu. Plus its not like you can't mount your thermalright laying down. You have another exhaust fan and then you could fit a normal NB heatsink

Exactly the kind of after market cooling I have.....except I don't have on my southbridge chip ={

Read my sig:D
 
I have no room for a tower HS on my P5B Deluxe as my Ultra-120 is occupying a lot of room. will a 40mm fan be sufficient to cool the NB post OCing?
 
you won't believe how heavy the board gets after those heatsinks plus gpu. I need to finish it off w/ thermalright mosfets which should come in this week. I wish thermalright had a cooler for the 3870 x2. I wanted to completely cool the whole thing just w/ thermalright. I should be sponsored or something ;)


Just enough room for A card, no way could you sli or crossfire unless you have a board w/ 3 pci-e

I'm trying to figure out how you getting that inside your case! What speeds are you running?

Well it does fit well...and the temps are 30/55 degrees celcius...and yes it is a tight fit inside the HP OEM case...but does good job at keeping the heat down!

I'm running @ stock!
I'm gonna get another motherboard soon and chuck that in and overclocking it up to about 20% increase!:D
 
You guys think thats bad? I used to be using an Asus P5N32-E SLI Plus motherboard. Solid board, not so solid for overclocking. The chipset idled at about 86C.

That is Bullshit....if it IDLED 86'C then the load would be 100+'C. That would burn your chipset down and your motherboard would not be usable anymore! ESP...when your system has not been overclocked and your motherboard stock heatsink is better then mine. Just no way...unless you touched it once and felt it very hot and estimated that it was 86 degree celcius and posted it here!

My stock HP motherboard's shitty little silver heatsink with 2 metal pin clips IDLED around 45'C and LOAD was 65'C.....I would need some kind of similar CPU cooling to keep the temps down...but then I got the HR-05 for $45 from an order...chucked it on with a little bit of difficulty and there you go....kept the temps down by more then 26% which is outstanding and when I get a fan attached to it....expect about 35% decrease drop which was about what I expected from my $45 heatsink. Thats when I knew that the TRUE was gonna be just as reliable because its another fantastic product from ThermalRight (Thermaltake):D
 
Good luck with all those heatsinks and rearranging things...It looks like that mobo gained an extra 20lbs with those sinks attached. :p

Ok, no trolling plz. I gave the board to a co-worker and I intend to set it up for him in the next couple of days. I'll reinstall Everest, and post screenie :).
 
First of all, what you just said is impossible to happen on a high end motherboard with copper heatsink cooling and also at stock volts and frequency!

Another thing that is harder to believe is that......you actually use......

Everset???? You actually rely on that as a Temperature monitor tool??? HAHAHA

Everset is not a correct tool for reading temps as much as Hardware Monitor from cpuid.com!

Download Hardware Monitor the latest one from cpuid.com and launch the program and then repost the temps!

An alternative to installing a 3-party NB heatsink could be to install a 120mm fan in the top 3 5,25" drivebays that you are not using anyway, I did this to drop NB temps on my p965 Commando and the effect was significant. An easy way to do this is to get a Scythe Kamabay :)
 
To the OP (if you are still around)

It appears you have a 120mm top blowhole fan. Heat rises. /hint /hint.

Turn the main heatsink so it is blowing up out of the top 120mm blowhole fan and flip the rear fan around so it blows in on the main heatsink. Reorienting the main heatsink like that will pull air across the NB heatsink and most likely reduce your NB temps significantly. The rear fan blowing on the main heatsink will reduce cpu temps too. This worked very well on a q6600 system I built, as it costs nothing but a little time it is worth a try to see if it works for you. If NB still feels hot you can get the NB cooler and the main heatsink fan will pull air through it without the need of a fan on the NB cooler.
 
I would do what Bill said. Then you could put the HR-05 non sli version on there and the 120mm fan will pull air into the NB too

Sounds good,Time to remount this AGAIN.
 
Alright its done,Nb is a little warm but alot better than before.should I have a fan on the bottom of the true 120 so its sucking air from the nb to the top of he case?
 
Depends if the fan is small enough to fit onto the of the TRUE and the little space gap between that and the NB HSF
 
I would say yes. From some experience, I notice my SB temps dropped when I put a fan on the NB causing air to move around that area.
 
SB temp drops?? Nah....the SB is nothing important really it is almost impossible for that to overheat but the NB comes into mind first!
 
I have one of those antc fans that have a speed controller and i just hang it from my zalman 9500 to blow over the NB. Ghetto but its works.
 
Hanging it from the 9500???? Heck its a good idea because I have fans hanging off all over the places in my case! :D
