Acceptable CPU temps under load?

[Disjunto]

Was just wondering what kind of temps are acceptable for a CPU (in this case PII X4 965) under load. Mine is currently at ~50c at load with stock cooling, but that fan is annoyingly loud and want to be able to lower the RPM a bit, so was wondering what kind of temp I should be aiming for? don't want to cook my CPU because the fan was too loud for me

those temps are fine, a aftermarket cooler will deffo help by a lot with sound and temp, those amd am2/am3 stock fans are annoying to say the least! Swopped to a aftermarket one and never looked back.

I know they are fine atm, I'm just wanting to drop fan speed and wondering what temp I should stop I'll be grabbing an aftermarket at some point, probably at same time I get new case,psu & gpu

85... I could turn my fan off... silence

Technically the max temp for these Phenom II CPUs is 63c - so 50 is fine.

Mine runs at around 49c under full load (940BE).

Ah right, guess I'll look into a quieter cooler. any recommendations?
