Cooling a Z68
Posted: Wed Feb 01, 2012 8:46 pm
Board is an ASRock Z68M-ITX/HT:
The stock NB cooler has a shroud with an "A" logo stuck to it with sticky-tape: I already removed this. Idling the machine (i5 2500K) in the BIOS has the stock aluminum heatsink at between 68 and 70 degrees C measured with an infrared thermometer. This is surface temperature of the fins so the temperature of the NB chip has to be a couple degrees higher than that.
I found this a bit alarming.
Does anybody have any experience with this NB cooler? It's called Cosmos Gold: http://www.amazon.com/Cosmos-northbridg ... im_sbs_e_4
I also need to provide cooling to VRM mosfets on the board, and I do have some 6.5mm wide sinks here that I intend to attach with thermal epoxy. Unfortunately there is no way for me to get my thermometer near the chips to register a temperature reading but I know I wonder if attaching heatsinks voids the warranty of a motherboard? I know this Arctic Alumina stuff is pretty permanent. One thing is that I'm worried that these guys won't do a good enough job by themselves and I'll want to come up with a custom built heatsink. Can I "place" the heatsinks on the chips using thermal compound, letting gravity keep it in place, just long enough for me to run the computer for a few hours?
