GPU block or full cover? Enough heat dis?

post #1 of 5
Thread Starter 
Does my VRMs and memory overheat if i buy a gpu block for my OCed 670? Do I need a full cover?

My CPU is 55 full load. Using a 280mm SR-1 radiator and 2x 5v Noiseblocker 140mm.

Do I need to add one more radiator to this loop or can i just add the GPU? I'm fine with a little high temps as long as it's stable. Butt keep in mind it's clocked to 1280/1755 @ 1.2v.. And CPU to 4.5 @ 1.2v.

Rule of thumb is: (# of Components) * (120mm) +120mm = Rad space required.

 

In general, memory and VRM temps don't overheat. And the GTX 670 doesn't exactly tax them that much either, even when OC'd. However, if you have a darn good clocker, and want to push it as far as you can, then a FC block would be arguably beneficial.

 

In terms of Universal vs Full Cover, FC blocks just tend to have better aesthetics (which lets face it, is one of the reasons you go custom water). However, with Uni-blocks, you don't have to buy card-specific blocks, which does save some money. But they look like crap imo :P.

Yeah, I must agree, when you buy just a block for the GPU (not full cover) it looks like crap. You will probably need heatsinks for the memory and the VRM, since there won't be a fan cooling them anymore.
Fullcover blocks look much better, and cool much better. They cover the entire card, including the memory and the VRMs.
If you have just one 280mm radiator with 2 fans at 5v, I think you will run into some heat issues, even though the 670 is quite mild in power output, your still pushing it. You can always opt to run the fans at 12v, and even then it would be high temperatures.
But I'm certain it will run, and it will be more silent than a high speed fan of the 670.

Okay, well it's because I think I'm gonna keep my 670 till we see some 20nm cards. Don't want to use much money on it. But it sucks having a aircooled GPU when I got water.. tongue.gif

Maybe i can find a cheap used 680 block or maybe I will get a cheap 290 and fullblock when price drops... Will 240mm + 280mm with fans at 5v give me decent temps with a single "highend GPU" like 290/290X/780/780Ti? Low noise is the most important for me. But i also want to be able to OC a little..

I wonder if NZXT's new Kraken GPU bracket, which is meant to work with an AIO cooler mounted on a GPU to cool the memory & VRam, could it be used with a universal GPU block instead of an AIO one? It looks to me like it ought to be able to be made to work ...
