Yeah, I was really surprised at the cpu heat. I triple checked everything and have some experience mounting heat pipes. Found out others had similar issues. I believe the heatsink design may be the issue, lacking enough depth or surface area for the heat generated (at least compared to my other builds using Zalman and Nofan hardware). Unless you plan to use a 25w amd am1 cpu (streacom makes a mount for it), intel's coolest running cpus with igpu are 35w. The Streacom 5 is much wider compared to the 8 so I don't know that it'll have all the same issues. Spreading things out should at least help with hard drive heat (theoretically). And the riser (if used) might add the extra beefiness the heatsink needs. Good luck.
