My Intel core i5 2500 is getting high temperatures

tomaskraven · Jul 8, 2013

Ive got a 2500 core in a gigabyte Z77 motherboard. When im playing for example dota 2, im getting temps up to 85 or 90 c° at some moments. Yesterday i removed the fan of the CPU, cleaned the dust in the fan and the copper like thing below as well as the core itself(there was like a thick dust layer sticked to both the cpu and the fan bottom part. Not sure whats happening. Should i set the fans to a higher PWM (currently at max 2.50 PWM/C°) ? Was this layer of "dust" something important that i removed? What could i do to lower these high temps?

Yes, it was something important. You`ll need to buy some thermal paste asap. You can get it from newegg, arctic silver is a popular name brand.

You`re system will definitely overheat without it, so get it right away. Once you`ve done it, you`ll be 100% good to go again.

Here is a decent how to vid: http://www.youtube.com/watch?v=pj8FDfDI5Y4

Is this the stock cooler, if so would replace it and get a decent third party one, or if keeping what you have, might want to clean things up and put fresh thermal compound (suggest Artic Silver) between CPU and heatsink

I'm afraid the "dust" you removed may have been the thermal paste between the CPU and its cooler. If so, please do not run your computer until you follow the following steps:

Option 1:
1. Buy a new tube of your favorite thermal paste (Arctic Silver 5, ShinEtsu, Arctic MX-4, Noctua, etc.; do some research)
2. Clean your processor with some rubbing alcohol and a cotton swab.
3. Apply the thermal paste following these steps

Option 2 RECOMMENDED:
1. Buy a new CPU cooler
I would suggest the Hyper 212 (Plus, EVO or X, whichever you can find). Great value.
2. Follow these steps with the thermal paste it comes with

Ideally, even if you follow option 2, you should buy some better thermal paste and apply it.
I would suggest option two.
Your temps will drop even more if you get a new CPU cooler, but new thermal paste may be enough.

If You had dust in between the heatsink and CPU then you weren't getting proper contact. Cleaning then reseating the heatsink with fresh thermal compound should fix your problem. Make sure the cooler is making full contact with the CPU.

its weird though, i only get those high temps when im playing a game or something, when im browsing etc, im getting 42 c°
I have 4 case fans btw. 1 intake in the front, 2 outlets at the side and 1 outlet at the back

When gaming, that is when your CPU is getting stressed the most. It is dangerous to your system to be running without thermal paste. I`d highly recommend not using your computer, and getting that paste back on there right away.

THANKS GUYS! Worked like a charm! Idle temps dropped down to 32 C° and not higher than 57 while gaming!
