Great PC air cooler for an affordable price!

Great PC air cooler for an affordable price!
After 2 years it was finally time to send the stock AMD Wraith Stealth cooler on my Ryzen 5 5600x out to pasture. They are decent entry-level coolers included with some new processors, but I was very dissatisfied with their overall performance, even after proper, quality thermal paste re-application. I don't even overclock my CPU, I just wanted it to run more efficiently and generate less heat. When it came time to look at a replacement, this cooler came highly recommended by the PC gaming community on Reddit and Facebook.The Scythe Mugen 5 is a great, affordable option for air cooling. It was super easy to install and came with all the tools/instructions you need. It even came with a little tube of thermal paste, which saved my behind upon installation, because I realized I'd lost my trusty XTM70 paste. While I'd have preferred to use my own paste, it was nice to know I have some that will tide me over until I upgrade my CPU down the road. There are tons of mounting options for this cooler as well, depending on the CPU socket, so just read the product description and ensure it'll fit your board.As for the numbers, I immediately dropped a whole 20c at idle (from 50-30c) which was pretty wild, but what really amazed me was its performance in intense gaming. In demanding titles like Red Dead Redemption 2, Battlefield 2042, and Modern Warfare 2, I regularly saw my CPU hit 95c with the Wraith cooler. After installing the Mugen 5, now it doesn't go above 60c (on average.) That is an insane 35c drop in temperature, in real-world gaming scenarios. I didn't think changing out to a more robust air cooler would entail such a HUGE difference but I'm glad I made that leap! I can game with confidence knowing my rig will handle whatever I throw at it, and when it comes time to upgrade, I know I'll be in great shape.My PC specs:-Windows 11 Pro-Azza Photios 250 ATX mid-tower case-Asus ROG Strix B550-F Gaming motherboard-AMD Ryzen 5 5600x 6-core CPU-Scythe Mugen 5 Black Edition CPU cooler-Nvidia 4070 FE 12GB GDDR6X GPU-Corsair Vengeance RGB DDR4-3600 RAM (64GB)-Corsair CX750M 80+ Bronze modular PSU-Corsair SP120 blue LED 120mm case fans (x4)-Kingston V300 120GB SSD (Boot drive)-Seagate Barracuda 8TB HDD (Gaming drive)-Seagate Barracuda 2TB HDD (Backup drive)

Passer d'un Stock CPU fan au Mugen 5 , c'est le jour et la nuit.
Qualité robuste, refroidissement génial apres plus de 6 mois d'utilisation avec un PC sous pas mal de stress.
Temp ne dépassant pas les 60 degrés en grosse charge dans un boitier non opti,
Hyper silencieux.
Un régal !
