I have a BlizzPPC
For me signs of 040 overheating show up first in apps that make use of the fpu, such as quake or amigamp, flashing triangles or simply amigamp crashing or the slider moving wildly.
I use pentium sink/fan in my power tower. theres probably only halve a milimeter between the fan and the tower case
but its deffinatly working as without the fan the fpu overheats and i have problems.
I tried overclocking to 33mhz, but the fpu trouble was worse and also i got crc errors in files.
