Summary: I've been building my own custom computers for over 15 yrs. I've always used a 100% air cooled system up until now. With recent high end cpu clock speeds in the 4ghz range air coolers have gotten ridiculously large and hard to work around.
Summary: Ok, I'll admit I made a mistake! I bought this without any fans and ended up using my case fans to push air through it. Surprisingly, the temp of my cpu drop 50 degrees. It rarely goes about 119. Mother board is now staying around 109.
Summary: I bought the H70 (with no fans, I used my own) off of Newegg with a $20 rebate, and it was a very good purchase in my opinion, although I didn't really see a good improvement until After I added a second fan.
Summary: Grabbed this in addition to a bracket from triptcc's website and was able to mod my GTX 580 in one afternoon. My temps were previously hitting 99+ degrees C under 100% load and this dropped the temps down to 60C max, with idles in the 30s. Much much improved.
H-70: Take your time with install, but works like a charm-

Summary: I bought my H-70 for a new build for my X-58, EVGA 560Ti, Intel:950CPU, 16GB Corsair memory, primarily for gaming and MS Flight Simulator X, etc. Also, I do a lot of video editing on Sony Vegas software, etc. At first, I must admit the H-70 was a bit of a hassle to install.
Summary: ~$100 for the H100, $80-$90 for the H80/70 the value of these units really cannot be touched. There are currently two readily available air coolers that can compete with these units. The Silver Arrow and the Noctua NH-D14.
Summary: Very Impressed with this unit. on a stock cooler for my apu a8-3850 temps were around 81f with the h70 its at 75f. i have it setup as push pull one fan bringin aair in and the other fan pulls it out
