Summary: These guys complaining about this cooler blocking ram slots aren't installing it right. If it blocks a ram slot horizontally, install it vertically. It fits fine so long as your case is big enough and you aren't actually paying for microatx boards. Nobody should be doing that. Stop it.
Pros: Be warned, this cooler is huge. I was actually joking with my friend while unboxing the parts to build this new machine about how the processor was the size of the entire box, or the ram was several inches wide, and then he pulled this cooler out its box and it really was the size of the entire box. I'm running an old CMStacker case and I had to break the tabs off of the cover for the aux case fan because they were hitting the top of this cooler. The top of it is a fi...
Cons: The fan is very cheap. Mine started making noise barely two days after I installed it. Luckily, it's a standard 120mm case fan secured with a couple of clips and I have a few of those laying around.
Summary: I really don't see why some folks came down hard on this cooler. I installed it on my ASUS M5A97LE AM3+ board with no pain. After reading the reviews here I was prepared for the worst and after 30 minutes or so had the board going back into the case wondering "What was all the fuss?" I do have a lot of experience building/modding PC's (like, 30 years) but I honestly don't think that 'helped' here, it was simple and straightforward.
Pros: Price w/rebate, quieter than stock, cools lower than stock.
Cons: None. I had no hassles that others mentioned. Yes, you do have to remove the motherboard if this isn't a new build, but that didn't bother me much.
Summary: Probably going to replace the stock fan with a cougar 64cfm @ 16.5 decibels and get my rig closer to silent
Pros: Cools my amd fx 6300 by 20 degrees on the high end, 10 on the low (I get 17 degree temps idle, 30 degree full load prime95 vs the stock cooler 30 degree idle 60 degree load) and I've overclocked from 3.5 to 4.5ghz. Includes clips for a second fan. Easy assembly (coming from an expert) took less than 30mins installing on amd. If you don't use the tape as I didn't it's a bit awkward getting the first screw started but after that it went together quickly.
Cons: Fan is a bit loud but tolerable, 1800rpm produces almost 30 decibels
Pros: Excellent cooling for the price. It was fairly quiet until the bearing on the fan went out.. If/when the fan goes out, it can be replaced with an off-the-shelf 120mm case fan.
Cons: It's a PITA to install. The process of unmounting my MB and trying to get everything lined up and screw.ed (thanks word filter) down without getting thermal paste everywhere took about an hour. After about a month, the fan started making a loud rattling noise. I had already thrown away the packaging, so I just bought a generic 120mm case fan and replaced the stock one.
Summary: Picked one up when there was a 20.00 dollar rebate, making my net cost < a Hamilton. Finally installed it with my Ivy Bridge i5 clocked at 4.3 ghz, replaced my aging Corsair H60. Cooling is comparable, but without the annoying pump on the Corsair. In my mid tower system I max out at about 81c running Prime 95. No complaints, until the fan really spins up it's not annoying. For the price, it's just really hard to beat this cooler.
Pros: +Decent cooling. +Inexpensive
Cons: Fan can get a bit loud when spinning at 100%. Thankfully, this only happens when your computer is really loaded. Normally it's pretty quiet.
Summary: Keep my 760k oc to 4.6 very cool. Max load at 100% fanspeed it keeps around 50C
Pros: For the price it's a good heatsink. I don't think there are a huge difference between heatsink's of this price and size, but the reason to go with this one would be that it has somewhat more depth than other offerings.
Cons: The fan in mine did not last, it was okay at first, still quite loud, but it's very noisy now at anything above 1400rpm.
