So right now im using 220 swiftech rads stack at the top of my 800d case and there doing good with my 980x and 5970 in the loop the liquid ideals at 32c and max out at 38c now anyways i was reading one 320 rad would do a better job than my 2 swiftech's put together what do you guys think and im also thinking about putting my 5870 under water.


this guy wants to trade for my thermochill 480 which is too big for my 800d because im not modding my baby

Well considering stacked radiators are useless, you really only have a single 240 radiator. Modding the top of the 800D is very easy, if you have a jigsaw you can have it done in about 15 minutes with little chance of failure.

Switching to that thermochill 480 would drop your load temperatures by 5-6C.

Even if you just sold your two radiators and got a single 360 radiator your temperatures would drop quite a bit.

Get the 360 and replace the 220 stack you have. It'll easily handle a cpu and a gpu.

If you don't end up getting the 360, you can split the 220 stack. Keep one up top, and put the other at the bottom by the PSU (you don't need to mod your case to do this. simply install the rad on it's side, by sliding it in where the lower HD cage is. You can still mount fans to it and everything).

man i was told a year ago from frozencpu stacked rads were the way to go.. but anyways so one 360 would pretty much smoke my 240's which is really sad considering how much the kit was when i bought it

the promblem with the jigsaw is its my dad's case and we have switch 3 cases being the 800d is the last case he said he will ever buy and he doesnt want anyholes drilled so i want a good 320 to put on top

If you look below the 800D, there's a huge mesh that pulls in cold air. The cold air is pulled in through there and exhausted to the back of the case (through the HD cage and through the big oval-shaped cable management hole), behind the motherboard and out the rear of the case. It works great.

The only other change is switching the fan at the rear of the case to intake instead of exhaust.

I would recommend a 360 rad, but the bigger the better IMO.

A 360 rad will be more than enough, and will probably beat your stack.
I run my 480, overclocked 980x, and full coverage board block on a 360, and my temps are fine.

EDIT: As a side note, I am running 6 1950RPM gentletyphoon's on it, push/pull.
post #9 of 27
hey crazy, what temps are you getting with that setup? I am considering 1 or 2 rads for 930 @ 4.3 and stock 5870
post #10 of 27
My 980x stays at 30-33*C idle, about 50*C full load (fold 24/7), 60*C on a hot day.
480 never goes over 50*C.
