VERY worried my cpu temps are too high, can't work out what's causing it

62c is the stated max temp for a 955BE and although I am sure higher wont damage it to much (depending on vcore) you are going to have some serious instability issues.. These CPU do not like heat! You can have a perfectly stable clock at 55c load which is unstable at 60c load..

for example I am running a clock under water 3.95ghz CPU / 2.7ghz NB/HT max load temps on the CPU is 48c.. exactly the same clock under high end air with load temps of 64c was totally unstable

Edit:
In regards to the poster that was asking for BIOS settings..

Off the top of my head for 3.7ghz ish you are looking at:

Vcore: 1.45
NB: 1.2
NB - CPU VID: will probably need a couple of bumps

You want to try and get you NB/HT running at around 2.6ghz you will notice a big difference in performance (you will need more NB - CPU VID for this)

Make sure that when you clock you get you RAM and NB stable first before you even touch the CPU, some 955BE have issues with RAM running over 1066mhz. If this is the case you want to run at 1066mhz and tighten the timings up as much as you can.. Only once you have your NB and RAM stable look to clock the CPU.. I would aim for around 3.7 - 3.8ghz keep load temps on the CPU under 60c.. keep an eye on your NB temps especilly once you start pumping more NB - CPU VID.. again 2400 - 2600mhz should be your aim for NB/HT.. its worth sacrificing 100 - 200mhz on CPU speed to get this if you have to

Ive got an Q9200 (2.33) over clocked to 3.1 and running @ 55c idle and 62c full load, your temps are ok and if they do get too hot your comp will shut down. any way if your that scared of high temps un-clock your speed from 3.8 back to 3.2?
 
Quick check have all you 955 guys run prime95 and seen it get past the first 3 tests? (1024k/8k/1k)

Case closed my 955 reboots @ 69 on the 1024 tests
Case open my 955 reboots @ 69 on the 8k tests (think it was test 8 or 9)
 
Crikey mine are 44 - 48 idle and 82 - 88 after a good 30 mins of Prime running all 8 threads 100% CPU. Ive been told thats ok though. And my case is massive (CMStacker).

Id be well happy with your load temps :)

Edit: and even after a good 8 hours of Prime its still 82 - 88.

I dont think its a problem.
 
AM3 CPU are totally different to i7 and socket 775 so please stop giving bad advice over what are "ok" temperatures. You are having reboots because your CPU is unstable because it is running to hot 69c is not an ok temperature for a 955BE 62c is the max temperature you should run at over this temperature you will get instability.

I am also not sure what BIOS settings OCUK have used for the overclock but I would expect a clock at 3.8ghz to need some NB vcore and NB to CPU VID increase to be 100% prime stable

I agree with some other members, try a different cooler with a fan to get rid of the heat.

The heatsink itself is doing the job by absorbing the heat from the cpu, its just it needs a fan to get rid of the heat off the cooler itself :)
