Made the cut, the heatsink now just barely clears the capacitors. Half deafened by the dremel.
Whatever the material was, it was not pure aluminum, it was a lot tougher, wear resistant and a bit heavier.
Edit: I am starting to think this build is cursed.
I installed the 750ti with the new heatsink and fan and managed to start my benchmarks, I got a bluescreen while installing drivers and the system locked up while I attempted to install Unigine Valley. After the reboot, the system refuses to see the SSD. (Mushkin enhanced 240GB)
Anyway, what I did manage to find out: The new heatsink and fan seems to work fairly well; it fits in the space with a few millimeters clearance. I didn't make the custom fan and shroud yet (too much going on), but I think it may not be necessary.
I've been getting idle temps of about 33C and it hit 64C in Passmark (Light GPU) In 3DMark Skydiver (Moderate-Heavy GPU) the temps got as high as 80C, which I don't consider to be too terrible, but still a little warmer than I am comfortable with. I'll try some readings from Unigine Valley once I get the rig up and going again.
Edit 2: The SSD came up after I left it unplugged for a half hour (while I was writing the last edit)
I'm going to run Unigine Valley (Heavy-sustained GPU) for about an hour or so and see what kinda temps the system gets to.
Edit 3: I think the system is right at the boundary of thermal throttling. Unigine Valley is reporting the temps pegged at 80C but is reporting both GPU and memory speeds at the max. of 1346 mhz and 1700mhz (5400mhz) I can hear the GPU and CPU fans kicking in to high gear.
Does anyone know if the clock speed readings in Valley are real time? the GPU temp meter appears to be.
Unigine Valley has been running for about half an hour now, no framerate drops yet (except for the initial burst when textures get loaded).
Let me know if any of you want any pics of the system.
