5.0 out of 5 stars Works with socket 1366 & Antec Skeleton case, May 17, 2010

This review is from: Cooler Master GeminII S - Processor cooler - ( Socket 754, Socket 940, Socket 775, Socket 939, Socket AM2, Socket 1366 ) - aluminum with copper base - 120 mm (Electronics)

I am kind of a CPU heatsink snob, and I tend to prefer the largest/quietest units I can get - but when I went with the Antec Skeleton case it limited by choices by quite a bit. At only 88mm tall (including the fan), this Cooler Master heatsink fit my requirements perfectly. Normally, I wouldn't have gone with a little unit like this - but I have been extremely impressed so far.

As far as compatability goes, this heatsink also works with the socket 1366 processors; even though it isn't specified in the info on Amazon. I'm using it with a Core I7 920 and it works perfectly - all the required parts for socket 1366 were included in the box.

One note on the installation is that you'll have to have the motherboard out when installing this heatsink. I'm not saying you need to pull it out just to install the backplate as with most other coolers - but you actually need to have the motherboard out when installing the heatsink itself; which seemed kind of awkward, but it wasn't very hard.

The first thing of note is that this is one of the quietest heatsinks I've used. I have other heatsink/fan combinations from Noctua, Nexus, and Zalman; and this is probably running quieter than any of those - even without adding a resistor to limit the fan speed! When I ordered this, I was planning on swapping out the fan with a 120mm Nexus, but it looks like I don't have to.

The cooling is also impressive. I run my main PC in extremely challenging conditions by keeping it locked up in a closed cabinet with only one 92mm intake fan and a 120mm exhaust fan that is venting into the garage. When you combine that with the summer heat in Texas, this is probably one of the most stressful conditions for a CPU heatsink. Even under full load, my Core I7 CPU has not gone above 160F (which may seem hot - but it's pretty impressive for the conditions).

Other reviewers have mentioned getting another type of thermal paste and I concur. Personally, I like the Arctic Silver 5.

Overall, I highly recommend this heatsink. Even if you don't specifically need a low profile unit, I think this is still a top choice.

3.0 out of 5 stars Works well, but .., June 19, 2011

This review is from: Cooler Master GeminII S Copper Base Aluminum Fins 5 Heatpipes CPU Cooler - (RR-CCH-PBU1-GP) (Personal Computers)

Installation was not good. It did not go well. Screws were not long enough or strong enough. They did not hold the plate on the bottom of the Motherboard flush or secure. After I got better screws from an old heatsink it worked fine. The heat pipes on this heatsink are not copper through and through they are only copper plated. Which I find to be cheapie. Even on a cheap $400 laptop you get pure copper heat pipes. Nevertheless, it does the job. It cools my phenom II x4 B55 3.2 Ghz good. No heat problems.

4.0 out of 5 stars Thermaltake Lanbox Lite + This Fan = Works, February 18, 2011

I only gave this 4 stars because of the installation struggle I had with the post installation. Putting in on the mobo wasn't that bad at all (I had to take it out, but it was fine.) The problem I had (and might have could prevented) was putting the usb connecters and 4-pin connector on the board which were all underneath the fan.

It fits nice in My Lanbox Lite with just enough room between my fan and the PSU. I was originally gettting the Blue Orb II, but on the day my item was suppose to be delivered, I got an email from Amazon stating that the item was out of stock and they had to refund me.

Anyway, the fan looks, sounds, and cools ALOT better that the stock intel fan that I originally had there. I have a Intel Core 2 Quad Q6600. With Stock, temps were 44c idle, as high as mid 60s load. With this, 36 idle, 50 load. I call that improvement considering the noise difference.

Edit: After further use, I used the 2 60mm fans that are placced the the inside to the outside of the vents to suck out the heat that lingers in that area (most likely due to the heat coming off of the cpu and out of the PSU that is DIRECTLY above the CPU fan. The temperature is now around the same temperature as the stock, but MUCH quieter, especially with my fan controller.
