Warning Make Sure you Measure your motherboard Slots before buying this Rad its 4.7" Wide, Covers Most RAM Slots on motherboards. I am Returning this Product for the T2 Version. (which is 1" Less Wide)

Experience: 1 Days

Cools well and is pretty cheap when on sale. It's also quite easy to install.
Very tight fit on my Evga X58 Classified 4-Way SLI motherboard, I don't think it would fit if the NorthBridge heatsink wasn't bent towards the PCIE slots by 5-10°.

I wish the TIM came in a syringe instead of a packet so it'd last longer.
I'm using two Yate Loon D12SM-12's on it and it keeps my Hexa-core Xeon X5670 d 3.5GHz 1.25V at 61c on the hottest core when running Prime95 Small-FFT's using the included TIM.

nice cooler
not as good as 212 evo, considering the two are close in price
good budget cooler, np at all with intel socket

Experience: 5 Days
 Verified Owner
-Good performance
-PWN Fan
-Can have some issue with some board, where the bracket can touch the VRM heatsink (H87-PLUS) and make a noise
GOod product overall, worth a 4 star!

It's Cooler Master.
Doesn't fit my AMD A99FX Pro board.
Cannot be turned around so the RAM couldn't fit in once the fan installed on my AMD motherboard. Poor quality of the product. Just save yourself trouble and go buy the Hyper 212 which I already use on another computer. Trying the T4 was a mistake for me. Completely Unsatisfactory.

Experience: 60 Days
just ok performance
only fits intel
for some reason not near the performance of the hyper 212 wwhich looks almost the same

Experience: 1 Days
none, you get what you pay for.
look below, for details
This product was just cooler master being lazy and making a cheap and crappy heatsink for intel mobos.( thats right it doesnt work on amd's. heat sink fins are two big(not able to have ram), also it doesn't support turning it around (unlike the hyper 212).

Experience: 5 Days
 Verified Owner
Well packaged
Good instructions
Comes with everything you need
It doesn't cool well enough for newer CPU's
You need low profile ram with an AMD socket
The computer shuts down because the CPU is overheating using only 60-80% of the CPU. The fan is facing down so sucking hot air from your GPU on an AMD socket. (probably does not help for temps)
I could add a second fan but if it needed a second one it should of came with it.

I won't even bother trying to return this to NCIX because I do not want to waste more money on this brand, I will just buy a product from a brand I trust.

big fan
replacement cools well
Defective heat pipes
first one was defective
Over heated my CPU till system shutdown
Got mine installed and Temps went crazy high all of the heat pipes are not working.
The system shut down to save the CPU at over 100c the base of heat pipes was so hot I couldn't touch it and cooling fins where cold and top of the heat pipes as well I re-seated it again with new thermal paste same temps.
I put my stock cooler back temps when back normal 38c idle 55c load
I couldn't believe the temps I have never seen bad heat pipes
Been building computers for 20 years.
I would recommend checking your temps with this cooler for first few weeks I will have to see if it's possible to RMA This with out the box and
I will re-review it then so glad my CPU is still working.

I got my Replacement cooler it works fine now better temps then stock cooler

Cooler Master needs to check there quality control I am not only one that got a defective cooler.

Below are reviews found on other web sites for this product submitted by customers.

Comment: "When pushed hard with a "power virus" like Linpack, the heat output can be as much as 180w according to the on-die power reading. The Hyper T4 reached a maximum load temperature of 62 degree celcius, which is way below the thermal throttling limit and a good result as regular applications and games
