Hey guys, first post here. Needing some help if anyone can assist. Recently bought an Arctic Freezer Pro 7 and after install seems like the cooler struggles to start up. Like there is a hesistation. When it does start up it spins really slow. Went to the BIOS and the RPM were around 500--600. I was thinking that the power supply is the cause. I have a 500 watt supply, the components I have connected are 1 hd, 1 dvdrrom and a low end graphics card. Do you guys think its the power supply or just a bad heatsink?
