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.

Great quiet fan for tight spaces. Amazing value for the money, thermalright seriously makes the best budget fans that I've tried other than Arctic which are great performance but look much more crude compared to thermalright's fans which look more appealing for the price. They move plenty of air even for being slim fans, this one worked out great as a rear intake for my GPU since there was a dead area there that cool air couldn't reach from my front fans. Highly recommend these any build!

I am using this with a 3D printed bracket to cool my AMD Radeon 7900 XT. Fans are quiet, and work great.

Great fan move amazing about of air for a slim fan. It's also very quiet.

For what you pay for these fans, they provide really great performance. I use these for an SFF build, and the build quality is pretty solid. -1 star because 1 out of 3 fans I ordered started to whine when mounted as top-side exhaust

In my ITX build I have to remove the fan shroud of my XFX 5500XT down to the heatsink and also needed 120mm fans that were thinner than your traditional size ones. These fit the bit. Attached them to a 2 to 1 fan header cable on the motherboard and cools with 5500XT with 0 issues.

It's quiet. It fits into slim spaces. It moves decent air. This is all a fan needs to do. This one does it without costing too much money.

Upgraded computer, upgraded fans, went bigger and more cfm. Uskng it as an air intake. The RGB is cool, have a program to change colors and patterns. Function is great and it is pretty bright, it's behind a grid but you can still see it well. Happy with purchase, would recommend.
