Scythe SCMN-1100 100mm Sleeve CPU Cooler

Pros: I almost did not buy this HSF because of all the bad reviews.... am I glad I did not listen. I installed the HSF on my Asus M2NBP-VM CSM and it is 100% compatible, even faces the correct way with the exhaust towards the back. The mounting mechanism is very simple. I was able to install the HSF in 30 seconds without removing my motherboard (Socket AM2). My 100% load temp is now as high as the idle temps with my stock cooler. I have a AMD 4600+ and my idle temp is 1C over ambient temp 29C and 40C at 100% load on both cores. Did I mention that the HSF is very quite, I have the ASUS fan control enabled which idles the fan at ~750rpm. I'm so glad I did not buy the loud and HEAVY Zalman fan.

Cons: I can't believe it is cheap, lighter then others and has no cons.....

Pros: It fits the socket F (if you have the more common smaller mounting---technically, the spec. also specifies a 4.1, but I've not seen in the wild). It's got the quietest stock fan of any heatsink I've ever heard! (and if that's too loud, you can swap a 19.2dB(A) Nexus 92mm fan for a cooling solution that will is next to silent...)

Cons: HUGE! Not for the narrow of case. The fins would radiate better if they were closer to the Ninja's wide spacing (and would produce less wind noise), but this is a minor quibble.

Overall Review: Go for this if you are on a budget for socket F quiet cooling. If you can spring for it, get the Ninja instead (if you have the case airflow to support fanless operation or need the air pushing power of a 120mm fan). If you want the quieter 92mm fan (and can't go fanless) get this one.

Pros: It definitely cools down the CPU and is quite quiet.

Cons: It's freaking HUGE. Also, the locking system it uses swings out too far on the bottom side and makes contact with my northbridge heatsink so it won't lock down completely without taking out everything, popping off the NB heatsink, and then installing it. It is pretty secure, though, no movement or anything.

Overall Review: It definitely does its job, and while it is big and a small pain in the bum to install for some people, I like this thing. People look at it and say "Woah what the eff is THAT thing?!"

Pros: Keeps my e6300 as cool as my case temps (around 29c), and it keeps it under 45c with a 100% load in TAT. Used arctic silver 5 and a scythe 120mm fan instead of stock.

Cons: Very tight fit on a gigabyte p965 s3 board, but it does fit just barely.

Overall Review: The 775 clips seem more well built than on my old heatsink, you can really tell when they are click.

Pros: Mounting procedure is not too bad, although full understanding of the clip system is recommended prior to mount. Supports a wide selection of fans, (almost?) matches Ninja performance for cheaper. Nicely lapped base.

Cons: Tall! Might be a problem for some cases, but fits in Antec P160, even with 120mm fan. Also, pushing the tensioners tightly into place can be scary when mounting in-case (mobo bends!). Careful: base is greatly scratchable.

Overall Review: Fits on Gigabyte 965P-S3, although touches and slightly bends a capacitor on NE corner. Make sure you properly align the black and white parts of the tensioners before you mount.

Pros: Excellent cooling at very low noise level,is compatible with all three sockets(Intel 775,AMD 939 and AMD AM2).

Cons: This heatsink is very tall, which if you have a narrow case might be a problem. Make sure you have enough room for this cooler.

Overall Review: I have a full inch to spare between my side panel and the top of the cooler.I have a mid tower Antec Case.

Pros: Actually very light. Looks like it would be much heavier in teh pictures... Very silent.

Cons: None

Overall Review: Keeps my Opteron 170 @ 2.6ghz at 35 idle with a case temp of 37c. About 40c while gaming in a 72f room. :) very happy with it...

Pros: Used it on my AM2 CPU for 5 months and it worked great. Just bought a Q6600 and it cut 25 degrees celsius off the stock cooler! Being able to use this heatsink on AMD or Intel is awesome.

Cons: Fins are a little sharp, but no big deal. I kind of like staring at the little cuts on my knuckles the day after wrestling it into place. :)

Overall Review: I applied Arctic Silver 5 according to the instructions perfectly (one thin line on the cpu) and my Q6600 cant break 50 celsius with prime95 small FFTs on all cores. Sweet.
