q6600 suddenly overheating
show user profile  horizon
So, recently I noticed my pc got much louder, as if it's in almost full load when it's not. When completely idle it's fine, but doing anything as little as surfing, the fan gets louder.

So I installed speedFan and it read core temps at around 79 celsius. This is the early distribution of q6600 and they were known to be warm, but 50 warm, not 80 warm, and it was at around 50 idle before.
So, I installed Intel Desktop Utilities to make sure it's not speedFan, and the cpu thermal margin is at aroun 20, which is pretty close to the yellow bar, and not good.

Here are all the readouts from IDU and SpeedFan:

Specs if needed:
CPU: Intel q6600 Core2 Quad, 4x2.4ghz
MBO: Intel iP35 BLKDP35DPM, socket 775
RAM: Crucial PC-6400, 800mhz, 2x1GB DDR2
VGA: Pci-e sapphire ati radeon x1950gt, 512mb ddr3
HDD: Seagate 320gb, 16mb cache, 7200rpm
PSU: Seasonic 430w, S12II-430HB

Pc is some 1.5-2 years old, never did this before, never overclocked.
I'm gonna try cleaning the heatsink and fan and changing the paste later today, but I don't believe that's it.
Heatsink is hot so I guess it's doing it's job (although I'm not sure how is 80 celsius supposed to feel like on the fingers, this is hot, but not unbearable hot), and thefan is spinning faster than usual, so I have no idea what's suddenly happening.

Any help appreciated

I would clean heat sink as you suggested and then try re seating it, see if things improve.

If you have to remove the fan in order to clean it, don't forget to clean off the old cooling-paste and apply a fresh one.

If you are using the stock intel cooler that "snaps" in, I would think some of your snaps just broke or let loose, those stock coolers are known for that. Make sure you are getting good pressure against the die (well I guess now its an IHS >> but whatever, same principle applies). Just take it out, give it a spray with some compressed air, clean off the TIM, put a small dollop of TIM on the IHS of the CPU, and then re-seat the heatsink.

This could very well be the solution, make sure to remove any dust between the heatsink fans.

A friend of mine stopped playing fallout3 a while ago because it kept crashing to desktop. After removing all the dustballs from the heatsink the game runs fine again :D

Aww damn, now I feel stupid about asking this.
Turns out it was just a dust clog right between the heatsink and the fan. Rest of the heatsink was clean, but no air got to it thru that dust layer.

Ah well...I deserve some bitchslapping...
