Nofan CR-80EH Copper IcePipe 80W Fanless CPU Cooler

It's quite big but not enormous. Attaching it is a bit fiddly but not terribly so - just make sure you have access to the other side of the motherboard. Importantly, once it is in, it has no fan and it does a decent job cooling down a CPU. It works well with my i5-11600. I would not use it with something that emits a lot of heat, though.

Had to send back... does *not* allow a VGA card in the first slot of your PCIe slots - would probably allow a low profile wifi card but I couldn't be sure. I ended up buying an almost equally large heatsink which is rectangular and (just) allows my graphics card to fit. This: Excellent - and allows me to cool my i8400 *passively* (i.e. I don't use the fan) Cooler Master Hyper 612 ver.2 CPU Air Cooler '6 Heatpipes, 1x 120mm Fan, 4-Pin Connector' RR-H6V2-13PK-R1

Tried to install it on my Ryzen 5600x In an open case (thermal take P3). CPU temps were over 70C at idle and shot into the 90s when under some load. Severely throttled! Covid was in full swing and I had a delay returning it ( couldn't return home for some time) The Seller (Extreme Hardware) was beyond rude when a return was sent and refused to refund. He was disrespectful and made baseless accusations against me. I tried to work with him but eventually had to resort to filing an A-Z Claim. Stay away from this product and buyer at all costs! I'm going to wait for a different fanless solution for my rig and keep the stock cooler on it for now.

Effective and beautiful, but fixing kit is poor. Screws too short.

Experienced user here. The cooler is small enough to fit my case without the plastic retainer - about the same size as a full size PCI card (my case is 3U tall). Easy to install, however some of the spokes has less areas to stick to the body - I suppose due to the manufacturing process - and those came lose. Performance is varied, maybe due to the CPU. It managed to keep a G3258, TDP 53W very cool (below 75C at full load), while on the other hand a 2500t (TDP 45W) would go above 95C even after reinstalling it.

How weird is it to turn on a desktop PC and have no sound coming from it? Very. I am using this on a home built PC. I have underclocked the CPU slightly to keep the heat down. Based on the benchmarks I have run, it appears faster than some overclocked PC's using better CPU's than mine, so choice of components when building a silent PC is paramount. This cooler does the job on my i7-4790K. It's running well under 40C, usually around 35C, at 3.8Ghz. If I buy some very quiet fans, I might overclock it, but with a 9 second boot from cold, I don't really see the point. It is fast and silent and this cooler was central in that goal.

Theorectically sound but dubious fitting techniques and overstating its compatability with mATX boards and DDR3 ram modules. The motherboard used was listed as being compatible with this cooler on the Nofan website. I agree with the other reviewers regarding the fitting. You have no way of telling if you have applied even pressure across the cpu/cooler interface. The screws lengths are barely adequate for an AMD board and the two of the retaining nuts for a mATX board and an AMD CPU are inaccessible even using Nofan's own chasis. Had to remove the board from the case to complete the fitting. Also be warned that this cooler is not compatible with standard Corsair Vengence RAM modules if used with a mATX motherboard,. The cooler 'squashes' against one of the ram chips forcing it to bend at an angle in its mounting.Probably would still work but this level of contact would mean heat being 'discharged' to one of the ram modules. You will need the low-profile variant of your chosen RAM supplier Brilliant cooler technology let down by poorly designed fittings and a lack of attention to detail in the compatability specs

Not sure if I wasn't paying attention or what here, but I mistakenly bought this for my Socket 775 processor. Unlike the previous version of this cooler, the CR95, this one does not fit socket 775 mainboards, only the newer sockets. Update: I used this heatsink for a while, but then went back to a more conventional large quiet fan. To my mind the extra savings in noise aren't worth worrying about the significant weight hanging off the mainboard. My PC is a tower. If it were a rackmount or desktop, I might feel differently, I suppose.
