The orientation of the HT-101 is dependant upon the orientation of your socket. I only realized this _after_ purchasing the HT-101, but in retrospect, I could've realized this earlier taking a closer look at the product pictures. For the HT-101, the intake/exhaust will be oriented in the direction o...

I have both the HT-101 and DP-102 coolers. Here are my quick notes about them comparively: Both are fine coolers. The low pressure drop design allows less noise per CFM due to less turbulence and fans to operate at higher CFM. Between the two: The HT-101 is definately better as it has more surface a...

I'm building a system with a BQE right now so I just tried a 38mm (L1A) on the front and it dosen't fit at all. It only has about 1.25" of clearance so you're limited to a 1" fan, max. This front fan mounting system on the BQE certainly isn't one of it's strong points. Personally, I don't use a fro...

56 C though! That's pretty hot for a P4. They usually slow themselves down at high temperatures.
P4s start to throttle at 100 C in automatic mode.

what is your fan setup? intake/exhaust? as a suggestion, before replacing fans, you may want to have your setup examined first to see if you can push air more efficiently before spending money. for instance, here is a simplified example of what i mean: look at a typcial flow vs. pressure curve for d...

you can always go out and buy a kill-a-watt for $40 bucks. it's a great toy to have anyway. it'll tell you your wattage, AND PF so you can figure out your VA.

basically: VA is AC power. watts is DC power, or AC power at unity power factor (PF=1). watts and VA is interchangable if your load is non-reactive (another way of saying PF=1). PF of non-PFC ATX power supplies is typically around .6-.7. i think some generics can be as bad as .5 though. use the simp...

NotSilentYet: if you're going to run a test like this again anytime soon, as a favor to ask, can you also include 5V skews? that would be terrific. i typcially run all fans that are not on dynamic fan control at 5V.
