M9i

Great cooler. Pleased with its performance. I'm using this cooler to cool my i5 6600K and it's doing a fantastic job at keeping temps within safe regions. The processor is overclocked to 4.4GHz and under OCCT/AIDA64 stress tests, the temp maxes at about 69c.For the price and size, it's great.The only issue I had with this was the hexagon screws sent to me were all so loose that they all came crashing down out of the backplate very easily. They would not snap-lock into place like they're supposed to making it impossible to get it mounted. I contacted Cryorig and they sent me free backplate and screws replacement and it installed beautifully after that.It's very easy to install providing you don't get bad hex screws. If you do, it can make things very difficult when trying to install the backplate onto the board.

I decided to go ahead and install the cooler without reading the instructions, I thought I knew what I was doing, I didn't I wasted 15 minutes as I didn't put the brackets the right way. Once I read the instructions it was fitted within 5 minutes. Keeping my i7 7700 nice and cool and the noise is barely noticeable. The only gripe I have is removing the fan from the cooler, it's a bit fiddly but you only need to do this is you are removing or installing the cooler to your mobo.

Bought this to replace the stock Intel fan.It's easy to install. I'm useless at just about everything but even I had it fitted in about ten minutes.I had to put the brackets on first as I couldn't fit it with them fastened to the mobo.It looks good and it's quiet.I don't have an unlocked CPU , so can't say anything regarding overclocking but my CPU is about 28c ticking over, which I think is decent.Would definitely recommend it.

Wanted something to replace the TX3 Evo that I had, which got very loud under loud.The m9i is miles ahead, very quite even at full speed. Instructions included were very clear and installation was very quick and easy to do.Using this with i5-6500 and idle temps are at 32c and almost never hits above 60c.Not to mention the excellent performance, it looks so stealthy with the black plastic top, hiding the metal.

Using on i5 3470, using stock cooler the temperature was around 60-70 under load. Cryorig cooler using aida goes to 65 and idles at 40. So there isn't a very large temperature difference, and the stock cooler is probably the better option for a while and then buying a more expensive fan. Yes it does run slightly cooler than stock but the difference is negligible. The fans do run quiet compared to stock. The temperature difference might just be my cpu though as others are saying they get larger temp drops

Fitting was a bit fiddly, but that may have been because I already had the motherboard screwed into the case - would be pretty simple to fit if you don't have the motherboard fitted in the case yetKeeps the CPU very cool, my i5 4590 is 35C at idle and rarely goes above 60C with full loadStays very quiet too, so overall a very good product at a great price

Bought for my locked i7 4770 after it started overheating on a stock cooler while playing intensive games. Overheating has completely stopped and I can make full use of my CPU. Some games the temps are down by 20 degrees!Can be a little fidgety to install though so finding a video of someone installing it would be a good idea

Excellent and cheap replacement for stock intel fan. Used with Noctua NT-H1 thermal paste my i7-3770k cpu idles at 30-33c (not overclocked) and reaches 60c under synthetic benchmarks (aida64). Fans typically spin between 700-900rpm and under full load 1500rpm.
