Looking at this thread has gotten me worried about my own CPU; especially after having my old one burn up after sitting at 60°C for months. Anyhow I modded my case today just for this reason. Tell me what you think and if it needs to be modded some more. PC Specs (only listed are parts generating heat): Asus A7N8X Deluxe AMD Athlon Thoroughbred 2100+ XP 1.733GHz Asus 8200 Deluxe 64MB Geforce 3 256mb DDR SD PC2100 RAM (2 of these) 512mb DDR SD PC2100 RAM 400w Power Source 30GB 7200RPM 40GB 7200RPM 1 Fan on Power Source facing back of case, 3500RPM 1 CPU fan Blowing on heatsink (both retail box CPU), 5200RPM 1 Chassis Fan attached to back of case, blowing out air , 3200RPM *1 Chassis Fan attached to front of case, sucking in air, ???RPM (around 5000) 1 PCI Slot Fan, blowing out air, ???RPM (around 3000) 1 Heatsink on Chipset nforce2 1 Heatsink and Fan RPM???, blowing out, on video card *The front chassis fan was added by removing the internal speaker then attached to the outside of the metal frame covered by the plastic front piece. Holes in the metal frame allow ventilation, so does a few holes in the front of the plastic front. The fan itself is off my old TB 1.4GHz. Running temps for CPU are: Min Idle: 33-35°C Max Load: 38-45°C Running temps for MB are: Min Idle: 26°C Max Load: 32°C External Temps in environment are: Min: 10°C Max: 25°C I've been thinking I might need a Drive Bay fan, and maybe a larger CPU fan, what you think?
