My system:

3200+ XP
Akasa fan (795)
A7N8X-X
9800 Pro
512 mb 333 DDR

After some initial problems (exploding PSUs!), I finally got this rig working.
I have never bothered about the cooling side of things before as I do not plan to overclock.
However, the exploding PSUs have made me think about it, as prior to exploding, one of the PSUs blew out very hot air very quickly.

Initially, I had 1 case fan blowing in (PSU fan blows out)the temperatures I was getting were:

Idle
CPU: 51c
Mobo: 32c

After 20mins of Far Cry:
Cpu: 55 -56
Mobo 34

After I added another case fan blowing out:
Idle:
CPU: 50c
Mobo 30c

After Far Cry:
CPU: 55
Mobo: 32

This morning, (nothing has changed, apart that my PC is 4 days old now):
Idle:
CPU: 47/8c
Mobo: 28c

After Far Cry:
CPU: 51/2c
Mobo 31c


Now, what's caused that - temp to come downafter a few days? And will I need further cooling? It seems quite hot for the cpu to be around the 50 mark all the time.

Thanks in advance.
 
well, wutever thermal compound u are using, has probly part way through its burn in period
 
Yes, your thermal paste has begun to "break-in". See Arctic Silver's website.

Important Reminder: Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.
 
The thermal stuff I am using is just the thin layer that was already on the heatsink when I bought it.
 
Same principle. It melts, fills in any microscopic voids, and thus provides better thermal transfer.
 
Many thanks. Too bad I just ordered a new HSF already. Would have saved myself £10 if I had asked earlier.
