So I have noticed that while playing BF3 my CPU (intel i5 661) is running at temps of 100-105C (core temp figures) while my GPU (asus ati 6870 Fac OC) is at ~70C. This is rather weird as the CPU normally runs at ~80C when at peak permormance. It is rather warm at the moment so that might be a reason. What I want to know, is this temp acceptable? and if not what solutions are there (heatsink cooling, liquid cooling ect.) and which type is suggested. I am using an antec three hundred case running the fans at full tilt.
 
Make sure your fans airflow are correct. Sounds very high for a CPU, maybe 80C max.. Have you over clocked at all?

Just try putting a fan next to your computer with the cover off :P
 
I haven't OCed it. What do you mean airflow correct? I've tied up any loose wires and separated the HDD so air can flow between. I wonder if it could be miss reading the temp? Any suggestions on good cooling, liquid or not and which brands are good?
 
Hmmm I'd think the PC'd freeze/reboot after reaching those temps? Could be incorrect readings?

What is the room's ambient temp like?

As for CPU cooler (if needed) best bang for buck is CM Hyper 212 Evo.
 
Ensure that your case has proper inflow and outflow fan configuration to create a proper flow of air THROUGH the case.

Also, use CPUID's temperature monitoring software or something similar, as opposed to the bundled software that comes with motherboards.

Those temps are to be expected though with bf3. A friend of mine with a haf922 and big 20cm case fans was hitting 90 degrees cpu temp while playing bf3 on a i7 2600k.

Last week I fitted a coolermaster hyper 212 evo (aftermarket cpu cooler) for him, and now his max temps are between 47-53 degrees after hours of bf3.

I would suggest fitting an aftermarket cpu cooler, as 100 degrees isn't too good for your cpu in the long run.

Your graphics card temp is fine though. Nothing to worry about there.
 
Download RealTemp, report back on what temps that gives. But at 100°C+ you should be experiencing slow downs, possibly even resets, so I'd guess whatever you are using is reporting incorrectly

Yup download a few more temp monitors, i know some temp monitors are not very accurate. Perhaps check what the temp monitor says idle and go check in the bios what that is reporting. Vga at 70 is not a problem.
 
Ok so I've tried some other programs cpuid ect. and it still maxing out at 105C, quite concerning. The only other idea I have is that the sensor is bust, anyone know how to test that? the reason I think this is that my CPU is normally cooler than my GPU. I have been play for a while and this only started lately. I have recently cleaned my PC, importantly the fins on the CPU cooler (stock intel) by swobbing it with cotton buds.

Any ideas are much appreciated and thanks for all the advise so far.
I am thinking of getting the Cooler Master Hyper 212 Evo what thermal paste is good to use?

CM 212 comes with thermal paste.

What RPM is your Intel stock cooler running at?

CPUID says 3375 RPM max, but I didn't know my CPU fan was adjustable, it has current and min readings so I suppose you learn something everyday.

Whoa, I'd imagine an Intel stock cooler would not be more than 2000 ~ 2500 RPM? Anyone?

Possibly incorrect CPU temps, incorrect CPU fan RPM? Not sure if I'm onto something here. :D
 
Wowzers, I wouldn't run the CPU at those kinda temps for any extended time. Really not healthy. Surprised it hasn't rebooted yet.

Anyway, I was also having temp issues after overclocking so I bought a Antec 920 water cooling unit. Works amazingly well. Dropped my temps significantly.

BF3 was sending my temps into the 90's and hit 100 a few times. With the Antec 920 I think the hottest it has gone is 55.

Not cheap @ +- R700 but well worth it.
 
dude, if your cpu is running at 100 degrees pop down to the spar and grab some bacon from the meat section

:D

jokes aside, that is DAMN hot. but with a stock fan maybe its possible?

I reckon you re-seat that puppy and see what happens
 
Something else is wrong here
That chip should be running like 50°C at stock full load. Are you 100% sure the cooler is seated properly? Did you take the cooler off to clean it? If so, did you apply fresh thermal paste?
 
Goliath:
Make sure that you've secured the CPU heatsink properly.

PLEASE TAKE NOTE that the arrows on the corners (of the stock Intel coolers) point in the direction that your LOOSEN the heatsink and NOT in the direction that you TIGHTEN it!!!
 
Dude before we go any further, do the idle test. Check the temps with whatever monitor. Reboot, go into bios and check the temp. If both are similar then follow what else has been said but i know intel has issues with their sensors, my q9550 for instance would not report correct temps. It always said 60 idle but in the bios it said 35-40.
 
Bios temps are not the same as idle temps, so that test is pointless. Not to mention that the bios usually (not always) reports Tcase temperatures, which are lower than core temps
 
So I did an idle test in the BIOS and it read 68C. All my Temp programs say ~42C when idle. It is pretty damn hot in joburg right now how much does that effect the CPU temp?
