core i5 overheating after a year of usage, how to keep it cool?

[shockblaze]

Hi, guys this is my first and ever thread (and i joined the forums today) wish me luck.

So, i recently got my os reinstalled (windows 7 professional 64-bit) and found
out that my pc keeps freezing completely and my keyboard and mouse stops responding,
after three days of investigation i pinpointed the problem, it was the cpu overheating.

Before windows could boot, i checked the bios settings and realtime temperature monitoring,
it was there that i found out that my cpu was 72" C! And slowly rising up, and it went as high as 89"C!

Wha could be the reason for this? Could u guys shed some light on this?

System Specs: i5 2400 (this is the culprit)
nvidia gt 520 (2gb msi edition) (ddr3)
24 gigs of 1333 mhz ram (ddr3)
1 Tb hdd and a 500 gb hdd
an intel DH67CL motherboard
and stock cooling
300 watt psu (im checking the secific model)


But do keep in mind, my age is 13+ only and im a student.

Thnks in advance!

Note: Right now im running my pc at maximum 20% usage as to avoid overheating.

I suspect something went awry with the cooler?

i verified that the cooler isnt the problem, its running perfectly and my cpu case is open as i type

oh and by the way its running @ 2600 rpm average is that normal?

Update: Im using speedfan to monitor my computer's temperature and here are my current readings
Cpu: 40"C
Voltage Regulator: 35"C
Memory DIMM: 41"C
PCH (i dont know what this is): 54"C
GPU: 39"C
HDD1: 35"C

But the moment i change my power plan to high performance (100% cpu usge allowed) my cpu starts to melt
@ 80'C +
HDD2: 38"C

How did you verify that the cooler is not the problem? If the fan on it is running at 2600 rpm, it's clearly not getting it's work done.

I think you may have to take it off, clean it thoroughly to remove dust and old thermal paste, and then re-apply thermal paste and re-seat the coler.

Or invest in a more powerful cooler while you're at it.

First, make sure no fans are full of dust or being stopped by a wire or something.

If that isn't it, obviously, the cooler is not doing the job correctly. Let's reseat it.

Buy some thermal paste, like Artic Silver 5, on Amazon.

1. Take off the cooler
2. get a cloth and some isopropyl alcohol
3. clean the CPU and heatsink completely clean of the old paste
4. Apply a vertical line of Artic Silver 5, about a mm wide.
5. Put the heatsink back on, and voila!

Hope that helps

Use HWmonitor and look at the core temps: http://www.cpuid.com/softwares/hwmonitor.html
