AMD Wraith Prism Cooler

Wraith Prism with RGB LED

Strong and Bright

The AMD Wraith Prism represents AMD’s ultimate cooling solution for air-cooled processors. The Wraith Prism goes where no stock cooler has gone before with per-RGB LED control around the illuminated light ring and transparent fan blades for movement and rainbow color effect control. It features direct-contact heat pipes and fan overclocking control to increase thermal effectiveness, too.

Unique Technologies

StoreMI Ryzen Master
AMD StoreMI Technology AMD Ryzen™ Master Utility
SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD StoreMI technology “combines” these two types of storage into a single drive and automatically moves the data you access the most to the SSD. Every AMD Ryzen™ processor is multiplier-unlocked from the factory, so you can personalize performance to your taste. AMD provides the AMD Ryzen™ Master utility to access this powerful advantage.

All in all very good CPU, and at this price point if gaming is not your be all and end all it's unmatched. Only drawback is the stock cooler can be a little noisy.

There are more powerful CPUs out there for sure, but the AMD Ryzen 9 3900x is one of the best available in this price range (although 5800x would also be worth considering if it were in stock, especially if you're thinking about pairing it with an RX 6000 series GPU). The 3900x should be a good CPU for gaming and multimedia productivity tasks. That it comes with a wraith prism cooler is also a nice plus. It's the first time I've gone with AMD over Intel, but it really wasn't a difficult choice this time round.

This is one down from the 3950X 16core. It represents relatively good price /performance. It does everything asked of it and the 3DMark CPU test return 55-60 fps. very smooth

Got this on sales, great product. It is a whole lot better than Ryzen 7 2700x. Well worth the money and can see the performance increase by a whole lot on benchmark.

Good product good price fast delivery


January 2020

Purchased it from well established suppliers CLL Computers tobe on the safe side if something goes wrong in the future. So far Im really impressed with this chip set. Its handling things with quite efficiency. So far Ive had no issues with it. Whatevers been thrown at it its handling pretty efficiently. I have nothing bad to say about it but rather compared to other countries UK price tends to be high for some reason. Especially for gaming this is what you want. Would never go for Intel chip set is because of the price and secondly since majority of us would never understand/ pick up on slight variances. Also, reason why I wouldnt go for the Threadripper. Moreover, buying a Ryzen 9 is to feel confident that its future proof for quite some years. Im my case, maybe 10+ years! Anyway, I didnt just buy this out of the blue; this took days of extensive research & asking others who understand pcs with probably their eyes shut.

Was the best place to buy at the time and was not disappointed. Not much else to say, the delivery was in time, noting was damaged, and I successfully built my computer. All round good experience


September 2019

Great fun. Bought it for machine learning problems. The mutlithread-able algorithms are a dream. Using Fedora 30. Had to install a bios update to get it to work initially but that was OK.


September 2019

The best CPU I have ever bought and such value for money ! Shame it's in such short supply but thank God I bought mine when I had the opportunity from CCL, awesome service, many thanks !!
