I have a home entertainment PC which is starting to overheat now that summer is comming on. Which I find strange as it is watercooled. I think it may be one of the HDD's? Using SpeedFan I get the following when at rest:

CPU: 31 C
Temp1: 29 C
Temp2: 38 C
Core: 11C

As soon as I put stress on the system by doing some rendering the Temp1 gradually climbs until the system become unstable and shuts down. All other temperatures stay well antruely within limits.

The specifications of the system are:
Microsoft Windows Vista Home Edition SP1 all patches applied
Motherboard: ASUS A8N-SLI
GPU: NVIDIA GeForce 7300 GT
HDDs: WDC WD25 00JS-55MHB0 and WDC WD25 00JS-00MHB0
CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4000+
Memory: 2GB
Cooling: Zalman Reserator V2
