Thought i'd do a review for this cooler in case someone is looking at it. I think Corsair gets a big pat on the back on this one. Between the efficient pump they've used and the big rad this is a great cooler for sure. I thought id gain some from it but its beyond what i thought by a good chunk. The rad is 457mm long so check that careful before buying. I run an intel 10900K and with a 280 mm cooler i had on it, that would give me roughly 28° to 30° C temps at idle.
This cooler gives me: 10% overclock @ 4.1 GHZ i have core temps as low as 19° C up to 23° C! Cooling fans on slow. At 4.8 GHZ overclock idle temps are still only 23° to 26° C. At 5.3 GHZ overclock idle temps are 25° to 28° C. I saw that and said wow. So after we put heavy load on all cores it never passes 60° C and in fact only one or two cores hit 60° C only for a second. So in certain load conditions like running cinebench gone are temps like 70° and 75° and up that we dont want if we had a choice.

Not a weakness really but one thing to watch out for when installing this. The pump head has a really light gauge single wire from pump head going to your CPU fan header on motherboard. Be careful routing this wire and dont snag it on a case edge etc or pull on it hard when hooking it up.

Nice job Corsair! Aweome cooler. I would recommend if you can fit it.
