NoctuaNH-D15S, Premium Dual-Tower CPU Cooler with NF-A15 PWM 140mm Fan (Brown)

This is an absolutely awesome cooler!.I was running a stock AMD cooler (with ageing quad core FX cpu) and regularly experienced idling temps of 45C. Heavy load would take it up above 60 and it sounded like a jet engine!Make no mistake, this cooler is HUGE taking up most of the space between the top of the motherboard (micro-ATX) and the graphics card.However in terms of height, it fits easily into my case (which is 210mm width) and there is still loads of room for RAM with even the tallest of heat spreaders.Fitting is a doddle and for AMD at least, makes use of the standard back bracket (which I didn't have to access) which it screws right into courtesy of a couple of adapter brackets. Bear in mind that you have to remove the cooler fan to attach the cooler to your mobo, but it really is no hassle to do so with a couple of quick release clips.So, a quick application of the supplied thermal paste, line up the cooler with the 2 adapter screws and tighten with the screwdriver provided. Re-attach the cooler fan and plug into the mobo and you're finished.The trickiest part of the whole process was actually removing the stock cooler from the CPU as it was practically welded to it with thermal paste . . .few scary moments but thankfully no harm done!.I have to admit I was sceptical as to how much difference in temp it would make and got it more for the promise of noise reduction, but I was amazed on firing up and opening the HW monitor that the first temp posted was 13C!!! - it actually went down to 5C before stabilising at around 19C . . .and this all in an old style case (PSU at the top) and only ONE rear case fan!Time to test it under load so I used a program called IntelBurntest (I know!) and ran the CPU at full load over a series of 10 short 1 min tests . . . Max temp achieved was 43C - amazing! I then tested it with Battlefield 1 (which made my previous cooler scream) and it got up to 41C before quickly cooling back down to 29C within seconds.The CPU is now happily sitting at 24C with minimal load. . .only a few degrees above ambient temperature.I can't recommend this cooler enough . . . yes it is pricey, yes it is HUGE, but you get what you pay for (and it is beautifully engineered and happens to look pretty good too). Having toyed with the idea of an AIO liquid cooler, I am so glad I opted for this instead . . .the near silence is priceless for me and no chance of leaks or fried motherboard/components! I can easily see me taking this cooler with me when the time for the inevitable system upgrade comes.To top it this cooler arrived promptly and within 1hr of delivery I had it fitted and up and running.

By far the best method of cooling.......so simple, less to go wrong (only a fan to replace). Have used many of these and all work extremely well. The offset design good for fitting in with other parts.I've actually never had to replace a fan even with daily use, so they last for years!

I was very nervous about installing this - having never built a PC before but it was remarkably easy, so don't be afraid of 'aving a go!'This is a beautiful piece of kit, both in form and in usage. No, its not got any flashy lights or spinning plates - but it is very well made, lovingly packaged and extremely good at what it does (and quiet to boot).Do note its huge! It just about fit in my mid-tier case, but really a full tower is probably a safer bet. Also note that this is for people really planning to thrash their machine! For 95% of gamers, a smaller, cheaper fan (Noctua NH-U12S is still overkill for most people I would say) will do the job and do it well.Otherwise if you are looking for one of the best air cooling CPU fans - you have the space and the budget - this is THE pick.

super piece of kit - no need for water cooling if you dont internd to overclock etc - this runs my ryzen 9 - 7900 with no issues when doing video work and heavy batch image processing.

Swapping out the Wraith Prism cooler I got with my motherboard for this one has seen temps drop much more quickly, my 5900x still gets hot under load but it dissipates much faster with this and presumably when I install a 120mm on the front it'll do even better, this has made me much less paranoid about temps. Virtually silent unless you're taxing a CPU even then it's a low hum at worst. Installation was easy enough on an AMD board, looks like Intel ones need a bit more fiddling with the backplate. The only mild issue I had was re-attaching the wire metal clasps on the fan back onto the heatsink after fitting while the board was in-case, the clasps quite robust however so a couple of 'almost got it' attempts did them no harm.

I installed this to cool an overclocked Ryzen 1700 on an MSI B350 Tomahawk motherboard, replacing the stock AMD Wraith HSF. A note - if you plan on doing the same, you will need an additional bracket for AM4 type motherboard mounting, which you can receive for free from noctua if you follow the instructions in the manual to do so, or you can buy one also on amazon or elsewhere. Here's the amazon link for said bracket: https://www.amazon.co.uk/gp/product/B01MTEFT52/The results have been beyond my expectations and then some (and this is from someone who already uses a lot of Noctua products).Temperatures at idle dropped by a staggering 15-20 degrees, and under load? Again, 15-20 degrees cooler than the stock Wraith cooler. And this is in a fairly small mid tower case to boot! As if that wasn't great enough, the noctua is also much, MUCH quieter - the excellent fan rarely needs to spin up by comparison, and when it does, it's still whisper-quiet.As far as clearance goes, you can see the indentations made to accommodate for RAM when looking at the unit, but to my surprise the height of the unit is such that these weren't even close to needed - there's no 'down to the wire' for RAM clearance with this, I suspect, unless you maybe have truly colossal sticks.In short:-Performance is incredible-Noise levels are phenomenally low, and a pleasant type that's non grating-Brilliant design that lets the huge thing fit where you might not expect it to
