Are my GPU/CPU temps too high?

Hi, I'm using a Dual-Core E5200 and a 8800 GTS.

While idling, my CPU temp is around 45C and GPU around 55C. After playing L4D2 for an hour, my CPU temp is 65C and GPU around 75C. Is it too hot? My fan can only spin about 1900 RPM at max speed.

Also, the GPU and CPU are not overclocked.

Thanks for the quick response, I'll try cleaning my comp.

Both are about 10°c hotter than my old setup (8800GT & E6750).

Are you sure 1900 is max RPM? Have you installed riva tuner to up your fan speed? As for the CPU, all I can say is consider buying a third party cooler like noctua or thermalright.d-rtyboy

My old x2 5600 got that high only when:

1. It was 95 degrees out and like 85 degrees in my room.

2. My GPU's 100C heat was steaming up the nearby X2 5600.

3. I had the worst ventilated case ever - one rear exhaust fan only, cluttered wires.
