CPU @ 4.2GHz Load voltage @ 1.592v
Ambient temp ~16c
Fans were placed push/pushPHANTEKS STOCK FANS SILVER ARROW STOCK FANS PHANTEKS TY-140s
The core temp is the one to go by and so the Silver Arrow performs better in my system by 1.4c on average. The Phanteks hit a max of 39c with stock fans and 38c with the TY-140s. The Silver Arrow had a max core temp of 36c. There was no difference in average core temp using the Phanteks with stock fans and using TY-140s
The base of the Phanteks isn't mirror polished like the Silver Arrow. Also, when cleaning the base I could feel tiny grooves in it. This made me think that I should have applied a little more TIM than I usually do.
I much prefer the Phantek's fan clips. They were a bit of a pain getting them on the TY-140s but once they were hooked up attaching them to the heatsink was easy.
I installed the Phanteks with the board still in the case and it wasn't a big problem however I am glad that my case has a hole behind the CPU because I needed to hold the backplate while I started the screws off. I also have a big case and couldn't have done it in my CM Sniper.It was much easier to install than the Silver Arrow and it feels more solid once screwed in properly.
I haven't tried the Phanteks TIM as I used MX-4 on both heatsinks.
Over the weekend I'll strap a UK3000 onto the Phanteks and see how much the temps dropEdited by tw33k - 1/10/12 at 2:03am
