Professional Universal CPU Water Cooling Block For INTEL/AMD Water Cool System Computer Clear (Transparent)

Pure copper heatsink. Nicely milled piece of acrylic. Make sure you disassembly it first, apply tiny amount silicone grease to main seal and tighten allen screws. It works perfectly. No leaks.

Nice fit and finish, no leaks, multiple mounting options built in. Great price compared to much more expensive units. No lights nothing fancy just a straight up cooler. Haven't set up mobo or cpu yet so I cant confirm how well it cools yet but will post an update later as i am running a leak test on my water cooler setup till it proves it won't puke on my new computer guts.Ok, so leak testing is done, no leaks! Fired up computer(posted fine on first attempt) ran it for awhile. This with a Alphacool xt45 80mm radator is keeping my fx 6300 @ 27*c during idle. (only 10* above room temp)Will be considering this for any future builds!

Received this system from a relative because it was being retired. Threw a new GPU in, and tossed an old noisy AIO, opted instead for a soft line open-loop system (CPU only) using this waterblock. Paired with a cheap 120mm radiator, it idles at 27-30c and never sees anything above 60c when gaming. I reused the AIO hardware and mounting plate because it looked better but the stuff it came with would have probably worked fine. Using a mix of distilled water and Peak Honda Antifreeze. Very satisfied with it so far (3 months of daily use), will update this as time goes on.

Works great, no leaks.Had to cut off the inner mounting tabs (round hole, not oval) to get it to fit on my motherboards (LGA 1155 boards) using a Dremel.Some notes:1) Gently tighten down the screws holding the acrylic on. Just in case they aren't completely tight from the factory.2) Mounting screw directions: Screw, washer, motherboard, washer, nut (this creates your stand-off bolts), then heatsink, spring, thumb-nut.3) Don't get carried away tightening that thumb-nut. The springs should NOT be completely compressed when done.

When I saw the price of this block I was unsure of what I would end up with. BOY was I shocked when this thing is cooling off an AM3 Processor to BELOW room temperature. Yes I said BELOW room temperature. The tiny pins on the inside of the block do a great job of helping to dissapate the heat from the processor. Under heavy load in testing and getting this thing up it barely got up to 40C, sticking around 37C and was back down to room temps in a matter of 20- seconds.I don't know how you guys are selling this so cheap but you are a godsend to have something this good for this cheap.(Edit) A full year later and this block is still running strong. No heat issues or anything. If you are on the fence about the two negative reviews? One of them didn't read if this fits at all and the other doesn't know how to build a liquid cooling system. Seriously. Read them for yourself.

This looked really nice. I wanted to use it in preference to the other waterblock I purchased at the same time. However, the ears on the mounting bracket make contact with the RAM on one side of the cpu and discrete components on the opposite side. I was not able to make it fit unless I cut the mounting ears. So, I will be sending this one back.
