Question: How many RAM Modules is this supposed to fit over? I am trying to find one for a 4 configuration. Most are for 3/6.
Document: My Cooling Fan connected Perfectly to my 4 Corsair RAM chips and the red matches the ASUS Maximus VII Hero ROG color scheme perfectly. The 3-pin molex connected to the mobo flawlessly. Its basically an 80mm fan in a fancy case. This is probably a luxury but it looks very nice. The instructions recommend this fan be used when all 4 DIMM slots are filled or in cases where overclocking or poor case air flow may stress the RAM heat situation. I don't overclock and have excellent case air flow. But I have this fan set to 100% and its whisper quiet.
Looks cool for a day or two, but rattles in my system. extremely annoying. I think the clips just don't fit on my ram clips right. Using Asus Maximus VI Hero, Corsair Vengence Pro RAM.
But if you happen to have a rattle just take a small screw driver to each of the screws and give it a small turn. If there is still a rattle just return for a new one. My Corsair Pro RAM chips stay near room temps constantly. I'd buy again for my next system and highly recommend to anyone.
This cooler is great. You can keep the red or change to silver or blue. I used the blue to match my 32GB of 1866 Corsair Vengeance Pro. Fan is a little bit loud at first but you can place on silent mode in the UEFI BIOS. Does the job and keeps the RAM cool.
If no other fan were running you'd no doubt hear it but it wasn't a stand-out from other 120mm fans in my case. Other reviewers have complained about rattling but I didn't experience that problem. The connection has rubber grips and attaches to the DRAM socket clamps. I cannot imagine how one of these would rattle unless a screw is loose or perhaps if a DRAM clamp is loose. If you're using any ASUS mobo make sure you use the correct clamp that comes included in the box. It must be installed in a particular way for ASUS boards but the instructions are crystal clear.
I ordered this fan to assist with a new build that had a dead airflow spot across my RAM, and being limited with larger fan locations that would solve the problem. I was showing 39c on my MB temperature location for the DRAM probe before installation, and now I am at 33c, bringing the location inline with the rest of my case temperatures. While this is a relatively easy install, it could be better. The mounting screws for the arms are on the underside. While being on adjustable sliders, you have to tighten them down to lock them in place.
The fans bearings are shot. as soon as I plugged it in it sounded horrible and put the DB's of my pc through the roof.

Works as expected. It basically just slides over the top of the memory and is held into place with the force of the arms. Seems somewhat stable.
Using this to keep the heat off my 1866 Vengeance. My system still hangs when they get too hot in a 80 degree room at 1866. Still it works great at keeping my temps @ 1600 below normal.
Answer: it is ideal for up to 4x memory modules
