Heatsink, Fan, and Stability testing!
On Monday as promised I picked up the Thermalright AXP-140 heat sink and a Noctua NF-P12 fan. I want to overclock my Intel, and I want it to be quiet. The Thermalright AXP-140 has the largest fin surface area of all the low profile heat sinks, and the Noctua fan is the quietest with the most CFM and Static Pressure. It's a glorious combination, but even on sale it was $90 after tax.
I haven't installed either of them yet, but it looks like I should have enough clearance (removed stock heat sink and "test fit". Worst case scenario, I remove my 80mm intake fan by the CPU, and put the 2 exhaust fans on the outside of the case).
After getting these components and playing around with them, I realized I didn't even know what my CPU and GPU are currently running at. The CPU is in a really good situation ATM, with an intake fan centimeters from it, and 2 exhaust fans perpendicular to the intake, it has lots of airflow. Running Folding@home with 100% CPU load it hit 40*C (33*C idle) with all 3 fans on low. With them on maximum, it dropped to about 38-39(30*C Iidle). Not much of a difference, but still good temps for 100% load. If the CPU was overclocked, this would surely rise, probably above 50*C, which is when the CPU starts to loose longevity.
The GPU on the other hand did not do so well. It looked like it had a capable stock cooler, with 3 heatpipes and a solid 80mm fan, but running a stability test in Furmark showed it peaking at 109*C, with visual artifacts appearing on the screen. Rival turner confirmed the temps, and in hindsight, I really should have bought a GPU cooler first. Either way, I'll be replacing that cooler as well when I do the install. Right now the Thermalright T-RAD2 and Xigmatek Battle Axe VGA Cooler are the top 2 choices. Leaning towards the Xigmatek due to HDT (Heatpipe Direct Touch) design, and price. The Thermalright is 10 more, and doesn't include fans. It also doesn't have HDT.
Anywho, I'm rambling. Here are pictures of the Heat sink and Fan.
Note, the heatsink was wrapped in a plastic bag, but I removed it to show what it really looks like.
Typical Thermalright base. Flat, but still has the microscopic grooves.

I don't know about you, but I really dig these colours.
Notches on the fan blades at different spots reduce noise.
Screws, rubber pins, 4-3 pin connector, and the LNA (Low Noise Adapter 1100RPM, 16.9dB) and ULNA (Ultra Low Noise Adapter 900RPM, 12.6dB).
