Hi all, couldn't find any designated tech thread, so this will have to do.

When I play BF3 I hit 98 degrees Celsius on my i5 2500k (stock speeds, stock fan).
My case is pretty okay, it's an NZXT Phantom.

Idle temps are 39-41 degrees C.

If this were a problem with the thermal paste and/or the heatsink, I'd figure I'd get much higher idle temps.

What gives?

Well it doesn't hurt to reapply the thermal paste, if you know how to? The stock paste isn't the greatest, and the i5s run hot to begin with.

That's definitely way too high. I agree that you should reapply thermal paste, and then check to make sure your temps are lower before running any more games.

Reseated HS, reapplied paste, and I'm getting 83 in BF3 and 90 in prime95


I'm a bit worried now, only had this machine for 2 months. Anyone know where the fault may lie?

Are you using a stock fan that came with the processor or something else? Know there are some fans that don't function worth a damn.

Yes, but surely they have to make it to some sort of minimum spec. It's ridiculous having a new CPU running with stock everything hitting the 90's.

Those are pretty dangerous and potentially damaging temperatures. Sandy bridge auto-throttles the chip once it hits 95^oC and 100+ it starts auto-shutting down to keep permanent damage from happening.

Yes...you are using the stock fan? Or you bought a fan and aren't using the stock fan?

Main reason I ask is fans aren't created equal and I have read posts on newegg about people using stock intel fans. Some say they have no problems while others say the heatsinks on the fan are crap. Though after you said you re-applied the thermal paste i'm stumped myself. Perhaps do a quick check to see what's running in the background + see what's running during the game.

You could try ordering a new fan for your computer and try that, but it maybe a bit extreme. One thing we're all in agreement with is once that svcker hits 95*C your computer will start auto-shutting down to protect itself.

One last thing I have to ask is when you are hitting those temps? Is it during intense fights or when you automatically load up BF3? Lastly, what settings are you running your computer on? Some games will rely more on CPU instead of GPU which maybe causing problems. *shrug*

Is there any noticeable amount of dust in any of the case's vents or fans?
What is the temperature of the room you have your PC in?
Is it isolated to your CPU or is there anything else (You should check your GPU) that is running hot?

Woah...i did your MB distort?

That it stupidly high for the 2500K. The stock fan is garbage. I think you can get a CoolerMaster 212+ for like 30 bucks. I'd look into that.
