KitGuru tried the Cryorig R1 Ultimate Cooler
A quote from the article:
Hot on the heels of our Cryorig H7 review we are looking today at the R1 Ultimate. A monster of an air cooler, the R1 Ultimate features twin 140mm fans, along with 7 copper heatpipes, while it measures nearly 170mm tall. If you want the best performance without buying a liquid cooler, could this be the answer?Cryorig R1 Ultimate Cooler Review @ KitGuru
