Gamma A40 ARGB BK CPU Cooler,100mm PWM Fan,133mm Height Single Tower Computer Compact CPU Air Cooler,4 Copper Heat Pipes,ARGB Function,Fancy Top Cover,for Intel LGA 115X/1200/1700/1851&AMD AM4/AM5

The Ocypus Gamma A40 BK is a decent cooler with good results and capability for a Ryzen 3700X (65w) and it looks good, even if the top cap is plastic. I must have gotten a little new product discount before the price increased to the current cost. It's size is perfect for the smaller towers and fits well. The 100 mm CPU fan is a good compromise between sizes of those 120 or 92 mm fans. When I sliced a flexible dragon using Cura the unit was capable of keeping the CPU below 77°C. It's working fine but you can probably do better with a bigger cooler and you're planning on using a CPU in the 125w+ range and having it pegged at a hundred percent. It's definitely better than the last tower cooler I used on a AMD FX6300 which was a Thermal take if I recall correctly. When the fan needs replacement I'll see what the company has available for it, and I'll design and 3D print something if I need to, but for the money it's definitely a very good and solid product to choose! I'd recommend it highly. No LEDs is a definite BONUS too. 😁

Why did you pick this product vs others?: Product looks quite nice and RGB is very well diffused. Looks pretty clean. Despite the small size, 100mm fan vs 120mm on a more normal tower it was great for the ryzen 5 3600 I used it for. Value for money: got it on sale and it was a great value for the price. Instructions were written and installing was quite easy Cooling: The included thermal paste was disappointing and I would recommend maybe getting aftermarket paste. Otherwise cooling was great on a mid range or budget cpu

Nothing short of the perfect upgrade over the stock AM4 cooler for only $20. Was incredibly straight foward to install and it has decreased my idle temp from 33 degrees all the way down to 23 degrees, with full load temp being at 45 degrees. Quality is alright and the fan isn't too loud.

Cheap, but surprisingly effective. However there are better options for only a few dollars more.

Super clean & runs cool, it is a smaller than average looking cooler but it’s still super nice!
