Thermalright C12015W-S CPU Fan Computer case Fan Quiet 4pin PWM ARGB PC Fan, 15mm Slimline Cooler Fan, 120mm CPU Cooling Fan(White)

Dateline: A Tiny PC Case, a Space Where Every Millimeter is a Battlefield, 4:07 AM. There is a special kind of madness that drives a man to build a computer inside a box the size of a shoebox. It is a high-stakes game of inches, a brutal, three-dimensional chess match against the unyielding laws of physics. Your greatest enemy in this tiny, hot-box world is heat, and your greatest challenge is finding a fan that can fight it without demanding a space you simply do not have.Standard 25mm fans are bloated, arrogant things in this domain. They are clumsy bulls in a china shop of miniaturized components. You need something specialized. Something lean, mean, and built for the trenches. You need the Thermalright TL-C12015B Slim Fan.This is not just a fan; it is a miracle of engineering. A scant 15 millimeters thick, it is a wafer-thin sliver of high-performance potential. When you hold it, you expect it to be flimsy, a fragile piece of plastic compromise. But it is not. It feels solid, premium, a dense and well-built tool that belies its skeletal profile.But the real shock comes when you power it on. For something this thin, you expect a polite, anemic puff of air. What you get is a hurricane. This slim blade moves a shocking, almost unbelievable amount of air. It’s a testament to some kind of aerodynamic black magic, a full-sized fan’s performance packed into a low-profile chassis. It’s the quiet, powerful engine that makes the impossible, high-performance ITX build a reality.In the cramped, claustrophobic guts of a small form factor case, where a heatsink is fighting for space with a RAM stick and a cable is threatening to choke the life out of your airflow, this fan is your secret weapon. It fits where others cannot. It brings a rush of cool, life-giving air to components that would otherwise be gasping for breath, thermally throttling themselves into a state of pathetic submission.And the value… the value is the final, beautiful punchline. In the boutique world of SFF building, where specialized parts often carry an absurd, "enthusiast" price tag, the Thermalright slim fan is a breath of fresh, affordable air. It delivers top-tier performance and solid build quality for a price that feels like a gift.This is not just a good fan; it is an essential piece of kit for anyone brave or foolish enough to venture into the world of ITX builds. It is the problem solver, the space saver, the silent, powerful engine that keeps your tiny, beautiful creation from melting itself into a puddle of expensive slag. A highly recommended, five-star champion for the small-box warrior.

This fan runs quiet, performs more than good enough for my use case, and the RGB lighting is good. All of this at a price I find satisfactory for the performance I get.For starters I got this fan for a niche case... I have an ASUS motherboard, x670e-a, that has an RGB graphic that displays near the exhaust fan spot on the side of the case. The fans I bought originally blocked this RGB graphic and it bothered me... I wanted a slim fan that that didn't block the graphic, but I didn't want to sacrifice too much performance to do this.I have a lot of fans in this build; I'm using a Hyte Y60 with an air cooled GPU, so I have 4 intake fans and want 4 exhaust fans. I replaced one of my exhaust fans with this one since I wanted a fan that didn't sacrifice too much performance, was slim, and looked nice in my case.

bought 5 of these for a new PC I was building. I was using a smaller micro ATX case, and wanted to avoid fans taking up too much space and interfering with my bottom slot on the motherboard, etc. These are no frills, no RGB, etc, but they work and are very quiet, which is what I wanted.

Great fans. I've been a big fan of Thermalright for a while, I needed some slim 120mm fans for my 360mm water cooler as full thickness fans were never gonna fit with my new motherboard. I was using some old as time ID Cooling slim 120mm fans that did the job until one started raddling. So after some looking I found these were about the cheapest and I liked all the other ID cooling fans I had used so I have them a chance. Honestly they're great, they are nice and quite and fit with the half mm of clearance my new motherboard leaves.

fan is okay, quiet for how thin it is but be careful, the hub where it mounts to the fan is really flimsy and can break easily

I needed thin fans in my micro ATX case and these worked perfectly. Even though they are thin they seem to move a good amount of air around to keep things cool. Highly recommend.

good price, works as intended

Fan is well built and feels high quality. The rgb is well done. It moves a fair amount of air and is quiet.
