Hi all. First time builder. After a day of nailbiting and indecisiveness I finally got my first computer going! But now I'm concerned my heatsink is going too fast/too loud. It sounds much more quiet until the bios starts, when it starts revving up. I want to make sure I'm not frying the CPU before I install an os - here's a video:
The fan should always spin at maximum capacity when in the bios since there is no cool and quiet or speedstep. Meaning the CPU will run at 100% all the time, needing additional cooling. Once you install windows or linux, the CPU fan noise should significantly be reduced once speed step or cool and quiet are able to regulate the CPU.
Considering you just might want to OC someday (I was in your shoes too before I found out how relatively easy it is to OC the i7), I would recommend this http://www.newegg.com/Product/Product.aspx?Item=N82E168... . If you buy a cheaper item now and then OC and buy something more expensive later, it will be more expensive in the long run.
