HIGH POWER® LGA-115x-mITX 1U Low-Profile Quiet 80mm Intel LGA 1150 1151 1155 1156 CPU Cooling Fan Mini ITX Micro ATX mITX PC i5 i7 Processor Cooler

Pretty great little heat-sink and fan. Relevant system specs:CPU: I5 3475SMB: EMB-B75ACase: Weird Acrylic "thing" off AliExpressI was looking for a cheap-ish CPU cooler, for a mini build, in a mini case... this did the trick. Great fan and heat-sink and at half the cost of the equivalent Noctua L9.Pros: great fan and heat-sink on a budget. Keeps the processor fairly cool. Idle (doing nothing) ~33C; normal usage (Netflix, Gmail, etc) ~ 40-45C; higher usage (games, etc) 55-60C. Not bad considering the price. I would have liked a few degrees cooler considering this is an "S" series CPU, but not terrible. I could probably knock off a few degrees with a Noctua L9 but at twice the cost and the L9 might not have fit my case, as it is just a touch bigger.Cons: honestly not many. I did notice that the fan is not silent, not overly loud, but not silent. Under load the fan is audible but not to the point of distraction. Oddly, the fan is quieter at a horizontal position than a vertical one... not sure why. The only other con is the coil-whine... yeah it is there; I did hear an audible coil-whine when I first started using this... it went away after about a week, but for a time I thought I was going mad... give it time and the coil-whine dissipates permanently (the whine is from the springs holding the sink to the board, I think).Overall, worth it!Just a note: I have seen reviews say they are using this for I7 CPUs and the like... I personally would not after the temps on my "S" series processor, but for lower watt CPUs, this is a good deal.

bought for KCMconmey 4 + 1 Bay DIY NAS Case and fits well and works well

Fan is quiet and just what I needed to replace my older noisy CPU fan. It was fairly easy to install as well.

works great. low profile so fits into a really small case. fan is loud even at quiet fan setting (- 1 star) in the bios but that's because the rpm is still high rather than the sleeves rubbing like "other" product heatsink fans. used a low voltage adapter to reduce the fan speed and set to normal in the bios . wow so quiet now. in normal youtube usage temps run around 36 c @ 1350 RPM with an i3 8100 . so it is good.

The SuperIO chip prevented one corner of the solder side bracket from being secured. I tried to trim out the part of the bracket that pressed against the chip, but the plastic is extremely brittle and the whole corner broke off the bracket. I managed to secure it only on two corners instead of all four corners and it seems to be holding just fine and the thermals look good and the noise from the fan was acceptable after several hours of CPU and integrated GPU stress. Not ideal but works.

Low profile and quiet. i needed to stay low profile for a NAS build I was doing. The orientation of the board does not allow for some of the more invasive cooling designs. This one is quiet. It came with the back of the board bracket and mounted without any issue. The fan seems to generate enough airflow and I've had no issues with my temperatures. Great value price as well.

This is a good heatsink cooler for the slim form factor PC case. I used this for i5 4th ten CPU, and I had no issues with dissipating heat from the CPU. Fan is very silent and does the job well.The only thing I would mention is that this cooler may not work for some of those slim 1U chassis. This cooler is about 30mm, and then add the height of the motherboard + cpu, so the total height will be around 40mm to 45mm to fit into some 1U chassis.

Worked great for about 2 years and failed. junk and do not buy. Other fans are on the market you can use. I have had fans in pc's last over 10 years and ended up being replaced because i bought a new case. no reason this fan should of failed.
