Hello... I purchased an OEM Athlon (Thunderbird) 900... along with a cooling device... the device uses Thermaltake's Golden Orb heatsink (this one is silver) and a fan that measures 50mm instead of the standard Golden Orb 45mm fan (the fan blades don't seem as long as the Golden Orb fan) and this fan runs at 4500rpm instead of 5500rpm. The device was sold under AOE's name, but I wasn't able to find this type of fan on AOE's website. I don't know if this was a wise investment... any ideas if it will do a good job in cooling the processor? Also, I was wondering if anyone knew of a refernce that gave the safe temperture ranges for a Thunderbird (in my case a Thunderbird 900). I've tried looking through AMD's website, but I've been upable to find anything. I powered on the processor... I know these get hot, but the temperature kept climbing to about 145F. I have no idea how hot this thing can run and I'm a bit paranoid in letting it run w/o knowing the safe temp range. Any help would be appreciated.
