Chipset Temperature

[Harris2508]

I just installed an Asus P5B MB with the E6400 CPU. Everything seems fine except the MB temperature (as reported by Probe) is running up to 47 degrees after the PC has been on awhile. I note the Northbridge / Southbridge are fairly close to the video card which is passively cooled. Frequently the MB temp is higher than the CPU. The case is a Lian-Li which mounts the MB upside down and has lots of airflow.

How high is too high for MB temp (or, more accurately perhaps, the Chipset Temperature). I'm wondering if I should be adding a chipset cooler.

Thanks a lot for any thoughts, guys.

I have an e6600 running on an P5w dlx and am getting roughly the same temps. I also wondered if the temps where a little high but eveything seems to be running ok atm.

Ok, I have an intel system with an Asus board, My Northbridge reads in at 39 on boot and slowly climbs to 42 which is where it stays.

My case is very small and has very bad airflow, my brothers system MB is at 35. I had a problem with my northbridge once where the paste had hardened and my mb was at about 70, i had problems but the MC Ran fine.

Do you have a heatsink on your northbridge?? because you should!!

I guess my prior experience was that the MB was always significantly cooler than the CPU. Frankly, I don't know how hot is too hot for a chipset. Since they do have heatsinks it seems reasonable that they would heat up.

Yes, this does have heatsinks on both the northbridge & southbridge.

Maybe I'm concerned about something that I should not be!

Thanks for your reply.

Very true.

I did some poking around and found an Intel document which includes the thermal specifications for the 965 Chipset. The link, if you're interest is:

It seems that the max temp for the chipset is >90 C.

I guess there's no problem.

Thanks for your reply to my question.

nope i woulnt worry as long as cpu is under 65 and hds are under 50 you are fine

I had the same question with my Asus P5B-E. The MB temp would stay around 50 with the CPU at 45 at idle.

I took a old 80mm fan and set it in my case blowing on the southbridge chipset and now the MB temp stays at 34 at idle.

I noticed that the southbridge heatsink is smaller than the northbridge and it is closer to my video card which is passively cooled.

I bet if you tried the same you'd get much cooler temps.

Well i use a P5B board and 3 months ago i decided to Oc my E6400 managed to crank it up to 2.80 before PSU started to get abit peedoff. So i decided to touch the north bridge cooler sod doing that again im still trying to grow back my fingerprints , i goto thinking why not stick a fan onto the H/Sink so i did a nice juicy 60mm-60mm 5000rpm 1 sod it only cost me 3 quid.

No problem with H/Sink being over heated it`s cold to the touch when i over clock the CPU(My own Preference) Dont try this at home Kiddies LMAO!!!!! :lol:

I have noticed that most of the Asus P35 boards i have bought will have a fairly high northbridge temp... around 35-50 depending... The higher end boards have better cooling and are cooler but if you have the low end P5B then there is no issues with running at this temp. If you are OCing suggest a third party HSF or even do as PFZ1 suggests and wack a nice little fan on the ah heck
