It’s summer and the heat is on. Some goes to the beach, some to Bagio, some goes to their hometown for their vacation. But for me (and my family), we’re staying at home (well, they spent a week in Laguna for a week of vacation).

With the currently temperature we’re experiencing here in Manila Philippines (from 28C to 35C), it is not impossible for many things to overheat. And since most are at home (specially students), one of the things that will be used most are computers. Unless you have an air-conditioned room, your computer might go freakin’ hot.

That’s what I have experienced lately. I am using an Intel Pentium D 3.2ghz system. At idle, the temps are at around 42C (before summer). But due to the current temperatures (we have no air conditioner), idle temp is around 50C. Playing games (need for speed) would make the procie go to a temp as high as 65C and my PC will buzz telling me I am reaching a high temp already. I tried changing the airflow on the PC, but nothing changed.

Last resort, check the processor’s heat sink for blockage. I opened up the case and removed the fan on the processor (I didn’t removed the heat sink as I don’t have any thermal paste on hand). To my expectations, I saw lot’s of dust covering the fins of the heat sink, blocking the air that the fan is blowing on it. I removed those nasty dusts and cleaned some other spots on the computer. Hoping for the best, I placed everything back, turned on the PC, and checked the temps, and idle is 40C-43C (waited for a few minutes and still on the same range). Then I played need for speed for a few laps (usually, I will hear the warning once the race begin), and heard no warning. After playing, I checked the temps and it’s only 45C-49C. I will still be testing tomorrow playing longer.

Dust accumulation on heat sinks are number one enemy on good cooling system. Cleaning it regularly is a good habit. Just make sure power is off and power cable is unplugged to avoid hazards.

Cheers.
