Help with watercooling

Phillstanyo · May 17, 2016

Hey guys, so I installed my first custom liquid cooling loop using the "EK Water Blocks EK-KIT P280 Performance Watercooling Kit" that someone on the forums kindly recommended to me. I've got it on my i7 4790k and set up was long because it's my first time but also because I wanted everything to be perfect (I will cry if it leaks and wrecks my build).

I first wanted to ask whether my temps were okay/expected given this loop. I'm using the Corsair Air 540 with 2 140mm fans in front, 1 140mm fan at back and the radiator on top with 2 140mm fans pushing. I am getting 60 degrees celcius on my cpu under full load using prime95 and about 30 degrees celcius idle. Does this seem like good temperatures? I've OCed my 4790k to 4.7ghz with 1.2 on Vcore.

Secondly, I've currently got a gtx 980 ti armour 2x and will shortly have a second one for SLI. I will wait a while and see what temps are like with this setup but ultimately will consider having the two graphics cards water cooled (adding another radiator to the front probably). Does anyone know of any water blocks that would fit the gtx 980 ti armour 2x? I've searched the internet and cannot find anything? Please bear in mind this is my first pc build and first custom water loop so I'm not as experienced

Those 980 Ti's are MSI, correct? According to www.coolingconfigurator.com, it does not look to be a reference PCB card, but it could be. Does the PCI-e connector have the nVidia logo near the gold contacts? Usually cards that are reference PCB will have this, but it isn't 100% the case.

If it is not a reference PCB card, you'll have to find a universal GPU block for the card along with RAM sinks for the MOSFETs, vRAM and VRMs on the card as they also need to be adequately cooled. Otherwise, if you can find a full cover block, that would be your best cooling option.

Universal blocks are good though - I ran MCW80's on my older cards for many years and they worked well. They were high flowing blocks and cooled very well. Like I mentioned, you will have to ensure the rest of the card components will need adequate air cooling.

Yeah they're msi, I got an email back from ekwb and they linked me this:
https://www.ekwb.com/configurator/step1_complist?gpu_gpus=1791
So it's exactly what I'm looking for ^^.
Like I said, I'll wait and see how temps are in sli and if they're really bad or a OC is required for smooth 4k,then I'll go ahead and order those blocks from ekwb and probably get another rad to add to my system.

If you go the watercooling route of adding your GPUs, you'll definitely want to consider adding an additional radiator to the loop, considering the TDP of a single 980 Ti at stock speeds is 250watts.

What rubix said! You should get 240mm rads per overclocked part, give or take.

Phillstanyo · May 18, 2016

So if I'm overclocking both 980 ti's and my 4790k then I'd need 3 240mm rads? Holy crap, I think my air 540 can only fit in two 240mm rads and maybe a one 120 rad at the back, then there would be no case fans for air flow :s

It's all about delta of the cooling loop.

Use the radiator estimation sheet linked below - it should give you an estimation on how many radiators in the 120mm format you'll need (or 140mm if you can fit them).

Nice sheet! Saved.
Small "bug": the multiplier on D-T 10 for 140mm at 0.5GPM is x1, instead of x2.

You never once mention your ambient temps, or you water temp delta t.....

In order to answer your question, one would need ALL the pertinent information. Anyone offering up anything else, knows exactly squat.

Sure enough - good catch. I made the correction.

Thanks.
