Summary: This thing is huge, you'll want to make sure you have room for it in your case. Definitely install on the motherboard before putting it in your case; you won't be able to attach it once the motherboard is installed. Some of the reviews complain about the magnetized Alan wrench. This should not be a concern, as magnets don't damage solid state computer components when there is no current going through them. Keep the wrench away from your hdd and you'll be fine.
Pros: Keeps my I7 4790k nice and cool (avg 31c). Quiet, nice looks, and does not crowd anything on the motherboard (asrock z97m killer)
Cons: Installation is tricky due to the size of the fins.
Pros: Fantastic performing heat sink, I have this sitting on my AMD FX8350. MB/Case details below Stock settings Rest: ~1C + ambient Load: ~18C + ambient OC - 4.4 GHz @ 3.6vcore (medium LLC) Load: ~ 24C + ambient Great numbers as compared to the stock cooler that comes with the AMD cpu (rest +8c/+40c at rest/load which is close to AMD's recommended thermal limit. Price performance is good but not great unless you get it on sale, then it's just epic which is what it is for me.
Cons: Fan doesn't make a big difference in cooling temperature when you consider the amount of noise it makes. From silent to full blast there was only a difference of 3C and that was with all my case fans on full blast as well. That being said, not a big con as I'll take a 3C hit for some peace and quiet. The cpu sits ~45C at load which is well under AMD's recommended thermal limit and thats fine by me.
Pros: The cooler cool efficiently. I have an amd8 6300 overclocked to 4.5gh and it does not rise above 50 degrees c during extensive stress testing.
Cons: The fan is not the quietest but hey, its no noctua. would be nice to make the fan clip mountable for replacement. The mounting systems is also not the best, and could use a lot of work. was not that easy to install.
Summary: My fan is starting to make noise after 2 years of operation. I would have to replace it and I am planning to remove the old one with it's bracket (it's a non-standard fan) and install in the slot between the fins a regular (squarish) 'normal' 120mm fan and attach it with plastic zip-ties to the fins/heat-pipes. I have had similar product from zalman before and it's fan also failed eventually. Their fans are flimsy but look nice.
Pros: Lasted for 2 years--I wanted to make a mention of it here. 100% Copper. It cools my 3.2 GHz (stock) Phenom II 1090T Thuban overclocked at 3.8GHz. I don't care about super low voltage and temperature--as long as it's stable and max possible overclock.. and it is, for 3.8GHz, at least, for this particular processor.
Cons: Fan is failing after 2 years of operation. I am planning to replacing it with aftermarket 'standard' squarish fan by sliding it in the gap and securing it with plastic zip-ties.
Summary: I had to jimmy-rig the cooler to get it to mount on my fm2+ socket. I used the original back plate and black screws. this mod. did not allow me to regulate the tension I put on the board as I tightened the screws. I gave them a "few good turns" and then checked behind the mobo to see how far they were protruding out of the back plate. I know, not very scientific or exact but I was determined to use this beautiful cooler with my new build.
Pros: terrific look. solid copper with nickel plate. offered with rebate.
Cons: very difficult to mount. rebate application has not arrived at rebate processing hdqtrs. not sure what happened.
Summary: The installation isn't overly difficult, it's just tedious and requires some patience and steady hands. Users who call it impossible or a nightmare clearly went wrong somewhere. I'm not mechanically inclined in the slightest and I managed to do it fairly easily; the hardest part was fishing out dropped screws or the occasional Allen wrench (which is magnetized by the way).
Pros: Keeps my i7 4790k very cool at around 30C even under CPU intensive programs. Compared to the stock cooler which hovered right around 60C, this thing is a definite improvement. The general build quality seems quite high, with the piping and heat sink and fins all looking very nice. The black finish that has been applied to the fins is a nice touch as it also dulled the edges so it's much harder to cut yourself. It's 'improved cooling effect' might be just marketing, bu...
Cons: The instructions are worthless, don't even bother attempting to read them (except in identifying your screws relative to your socket type). There are plenty of Youtube videos with step by step instructions that are ten times better and simpler to understand. The screws are not separated by socket type, nor is anything really packaged. It's like the company just tossed in the components without any real thought to organizing. The red LED is laughably dim, barely notice...
Summary: Any other problems arise and I'll let you know, but so far this is an awesome product.
Pros: Decided that I was too lazy to take my motherboard completely out so I left it in and did the install. It was actually quite a bit easier than I expected, had to take a couple of my RAM cards out to get the screws in, but was only ~30 minute install. With my stock Intel cooler my CPU was idling at about 40c. With the Zalman I'm sitting at 27c idle temp. Doing the full OC test only brought it up to 40c. And last but not least, it looks awesome
Cons: It's not something that I'll take off an egg for, but it just BARELY fits into my Rosewill Blackhawk ATX tower. The top of the heatsink sits about 1cm away from the fan on my chassis door.
Summary: The cooler works well. I tried to get my hands on a red LED version but they tended to be 20$+ extra, which i found not to be worth it. The installation was going well until I hit the last screw in the upper back corner of my case (Corsair Carbide Spec 03). It was TIGHT and I wouldn't have been able to get the tool or the screw in place unless I removed the back case fan.
