my two front fans on the NZXT Tempest dont seem to push enough air even though i cleaned out the filters. So i bought a fan extention splitter, so i plugged the two fans to the motherboard. Then i tried to use speedfan so make the fan go faster, but i dont know how. can somebody help me use speedfan? i tried fiddling with the things, but nothing seems to change. i watched some tutorials on youtube, and on speedfan, the 3 fans (i think its the cpu fan, and 2 front fans i plugged in using the splitter). and on speefan its already at 100% and its running really weak, and when i change it to like 50 or 25 percent, it doesnt change. so im doing something wrong here. any help?
