Okay i just ordered this kit H20-220 Ultima XT with dual rads and vga blocks does anyone have a estimate how cool my system also i will have 4 fans on the rads so will this keep me cool???? overclocking my 2 xfx 5770 video cards and my 965 to about 4.5ghz

No, not eough rad. Your CPU won't be very happy when your gaming.

^ You pretty much need a 220 rad for EACH GPU. Another 220/320 rad for the CPU. So a total of 3x rads.

Also, I'm assuming you are replacing that cr@ppy Thermakcr@p water cooling set up?

yes i got rid of the thermal take sh*T i guess since i ordered 2 we will see what the temps are do you think there going to be bad or is 2 ok but 3 is what really is needed

You will need at least a 220 just for the CPU, depending on your ambient, though you would be best served by a 320 to give you overhead since you plan to overclock, and you have no idea how much you have to increase the voltage to get your target overclock. If you do go with a 220, you might find that you have to really crank up your fans or your heat will start to spike, depending on your ambient. At least with a 320 you have a better chance at keeping the 6 fans in push-pull config running low & quiet.

The 2x 5770 you have in crossfire will need about the same level of cooling. Shadow and Conundrum both know their stuff. Standard stuff...go for the full coverage blocks if you want to spend the money, you MIGHT see some cooler temps by a degree or so, but for most situations, just get some good VGA water blocks and use ramsinks to cool the memory. Some people like to cool the MOSFETs, but my belief is that those parts are designed to run hot...put a heat sink on it and make sure there is a fan passing air over it since the video card no longer has a dedicated fan. Same with the power supply MOSFETs for the CPU on the mainboard as well as the NB, SB and memory. Yes, you will still need case fan(s).

You have 2 220 rads?
A single 220 rad will cool those 5770,s just fine.
My 220 rad cools my 2 4890,s just fine too.

A single 220 rad for your 965 will work just fine as well
if you run a better CPU block than the TT.
But i doubt you will get the 965 to 4.5ghz, maybe 4.2.

im at 4.2 i have fans on the memory umm so im thinking you guys are saying im perfect now im gonna show u a pic of the current water my new stuff will be here friday

4.2 already? Not bad, if you can get her up to 4.5 make sure to let us know. :)

yeah 4.2 not bad at all umm my max was like 64c and idle was like 40c so im hopping for atlease a 10c drop since i will have more surface area better cpu block and i will have a total of 4 fans on the rads push pull

Ah you are going to be stacking the rads?
2 separate rads would be better in a dual loop config,
but those stacked rads do help, ya just need good airflow
over/under/between them.

Yeah the ST XT CPU block is one of the best out, it should be
much better than the TT kit ya got now.

yes i will be stacking them i was planing on the putting 2 fans in the middle and 2 the back of the rads

Don't know about you, but there have been more than a few cases where cards (mainly the GTX260s/4870s) where just RAMSINKS/MOSFET sinks were unable to keep them cool and were crashing so I'd personally would go with full cover blocks now.

Yea pretty much, it is reccomened to use a (meanwell) PSU for TEC.
They have thicker gauge wires to handle the load from a peltier.

With a good quality regular PSU you can get away with it but ya
need to replace the wiring that will power the TEC with heavier gauge.
And use quality connectors.

Uhh i guess it is ok, WAYY overkill for what you have.
But if it doesn't commit homicide when and if it commits suicide
then you should be ok. :)

Hey shawdow is this what i need to be at 4.5ghz or do you think its possible for what i ordered

TEC cooling is a compleately different animal that water cooling. There is a LOT more to TEC than just getting a big PSU. You gotta think about wire gauge, max power draw, QMax,etc. Same goes for other forms of cooling such as phase change, DIce,etc.

I HIGHLY recommend you read up on TECs before even thinking about cooling with TECs.

Stacking the rads, even with your fans will only give you a total of 120.3. Unless you run some 2000 RPM 38 mm thick fans in push pull. Then a bit more. The tests have pretty much panned the stackable rads. Not worth the trouble.

Been lots of feedback on them in forum discussions when they came out and users tried them.

xtreme forums is where Skinnee pretty much call his home.
