Just upgraded my PC a little. Upgraded ram to Corsair 12gb (3 x 4gb) ddr3 1600, added a Blue ray burner, and finally bought some fans to finish my cooling system. :D

8 x 120mm (44CFM, planning on upgrading around tax time) Furmark extreme 1920 x 1080 8xAA, top card 52C max, bottom card 58C max (ran it for half an hour, temps stable). Before during gaming BF3 bottom card would hit 65C, curious to see what temps actually are during gaming, haven't had time to play yet, been so busy. Haven't overclocked cards yet, i'll post when I do.

I have the top fans wired to a switch, so i can turn them off if i'm not gaming.

Dang..2x 4x120 rads? What kind are they? Slims, but you are looking at close to 700+ watts, potentially for each? That's some significant over-radding right there. I like it.

What are you running for blocks and pump?

For those temps, you shouldn't be seeing that, I wouldn't think. Do you have air anywhere (rads)? Good flow? How are you flowing your GPUs...serial or parallel and what blocks? Should be ok either way, but just curious.

What did you use for standoffs for the rads?

(Looks a LOT like my previous setup, but I was running dual MRC320's)

Edit: Oops, yeah koolance 4x120mm

Says 1300watts cooling each radiator



Running in serial

bottom one is a DangerDen Gtx 480 waterblock, The top one is an MSI GTX480 Hydrogen with a AuquagrafX cooler

I'm using nylon 1/2" spacers between radiators and side panels.

:D

Haven't tried mounting fans for suck, but I'll give it a try when I get time.

Must be Koolance rads, then, if they advertise 1300 watts. I was breaking this down for someone the other day, and basing the move from 3x120 to 4x120 rads on Skinnee's charts, they would only realistically handle 700-800 watts given a linear surface area increase. Koolance also says a 3x120 rad can dissipate 1000 watts, which can't possibly be true without very, very good fans, very good flow and the magical power of unicorns. While they are good rads (dense fin design) and the potential they have a more optimized tubing pattern/design, I call farce on their 1300 watt claim unless they have specific information that provides scientific proof they managed to dissipate that much heat with them.

right right, i here ya, I agree, don't think they can handle 1300 watts, but they work for my purpose. I picked these radiators because I wanted the hose to come out the back instead of the side. I actually only wanted one radiator, but one came dented due to bad packaging, so I was gonna send it back, but Performance-pcs sent me a new one and said to keep the damaged one, so I pressure tested it, and it was still ok, so I just used it anyways. Thats why I got two, and only had 4 fans at the time. I was broke.

As far as cooling, I thought any quad radiator should be enough (had only one gtx 480 at the time).

Don't really know what else to say... meh... LOL

Thanks I needed a lot of heat displacement and also the ability to go silent when I wanted to.
