![]() Its not perfect, but then again given the budget and the quality of the tools used (none of this is industrial/professional grade, this is more your weekend DIYer enthusiast type project) it's actually kinda surprising to me how decent the results were. There is a fourth fan not shown in this photo, it was placed on top of the PSU to keep the PSU temps minimal while avoiding the PSU needing to kick-on its own internal cooling fan (which would have resulted in a non-linear power-consumption response for the system). The fans were normally placed on an adjacent platform below the desktop level during the tests. ^ the red dot you see on the NH-D14 finstack is from a built-in laser pointer on my IR gun, shows you exactly where you are sampling the blackbody radiation from for purposes of establishing thermal temperatures.Īlso in this photo you can also catch a glimpse of the fan array of dummy fans I setup for power-consumption continuity purposes. In cases with low clockspeed and/or low Vcc, where the NH-D14 was actually sufficient to passively cool the CPU at a temperature under the TJmax limit, I would go to the extremes of putting a card-board box over the top of the NH-D14 to force the issue of getting the CPU to heat up:Ĭlockspeed (GHz),Temperature (☌),Vcc (V),Power-Consumption (W) I would repeat this process until the CPU hit is TJmax of 98☌ and started throttling. Then I'd let the temperatures level off, I'd record the temperature and power-consumption, and move the fan again. ![]() ![]() Once the temps leveled off, with the computer fully loaded with IBT (4 threads, affinity locked to physical cores) I would physically move the box-fan a small distance away from the computer in increments of roughly 6-12 inches at a time. What I did to control the CPU temps was I started IBT for a silly long session (300 minutes) with the boxfan close to the NH-D14. ![]() ^ The box-fan (not really a box-fan as you can see, but I forget the technical name for this thing) can be seen in the background there. ![]()
