I think I have a heating issue with my Dell GX280 system (at work). Whenever I use a "big" application (like Adobe), this thing starts screaming (fans run at full speed I guess) and I can feel the heat waves coming out of it. The air flow is very fast in the back of the case. Tried checking temperatures in BIOS, they don't have that facility in the BIOS. This is the system cofig: Pentium 4 3.4GHz (560) 1GB DDR 400 Dual Channel Radeon X300 256MB 160GB SATA HDD The system never freezes, nothing strange happens, just the "lawn mover" noise everytime I do something serious with it. Can somebody guess what's goiong on? This has 3 year on-site warranty. When I contacted "award winning" tech support, they asked me to take the system apart and test what fan makes the noise My guess is that this is either a BIOS or motherboard problem.
