During the autumn part of 2020 I decided its was time to swap out my current pc case for one that allowed for better space and cable managment. Ended up with 2 case options caselabs tx10 or thermaltake wp200. You can guess which one I got cause its the only one I could find available new and and an extra P200 to go with it. I’d still buy the caselabs tx10 if someone sold them new or used.

Then ran into a delema. My current corsair hydro x custom loop is not sufficient enough for my pc as I have a mid-high idle 37-44 C. Currently I can’t really complain about the corsair stuff it does the job well. i want something a bit beefer and down the rabbit hole go again.

My question is what is better for my cpu 480mm vs 560 rads? I plan one using EKWB rads and pump/res combo along with the optimus absolute trx40 cpu waterblock. Next problem is which fans to use as I like corsairs rgb fans these product which led me to buy their custom cooling kit. I want to keep the same rgb contollers and other items. EKWB pump/res combo units have their own rgb as well as their vadar fans with rgb. I like the corsair rgb aesthetic but is it better to go with EKWB’s fans for rad cooling?

The EK Vardar fans are designed for high static pressure, but otherwise nothing special. Any fan intended to go on a radiator should be fine.

By the way, those idle temps don’t strike me as particularly high for late summer/early fall, but your mileage may vary. My 3960x idles in a similar range when ambient temps are high. (It’s on a custom EK loop with a 280mm radiator.)

It’s not just about radiator size… There is thickness, fins per inch, ambient air temperature, and how much air you’re pushing through them(this would be CFM measured from the radiator, not the fan).

All things being equal, larger radiators, delay the time before equilibrium is hit, or allow you to get away with fans less than capable of what you need.

All this being said, you never mentioned what the current radiator is that you have. Are you presently running a Corsair 240mmx30mm ?

Currently a 360mm x 54mm thick Corsair Rad. I want to go with the best rads and pump/res combo I can to match my build concept. This is my inspiration and the build name is:

The Cascade.
