How is this for a WC setup?

Dumphole · 3 Sep 2016 at 18:02

Hi all,

I'd like to run this past you guys if I may. I have a Phanteks Enthoo Evolv, a 6700k and sli FE 1080's.

I'm intending to water cool the lot as its sill noisy. I wanted to use a 360 rad up top and a 280 rad up front (two 360's is a REAL squeeze). The circuit I intended to use was 1080's - 360 - cpu - 280 - pump - -1080's. The pump I wanted to use was the DDC310.

How does that sound?

Ok that's reassuring thank you. Is the pump man enough for the 3 blocks and 2 radiators?

Dumphole · 3 Sep 2016 at 18:35

I should add its a pump/reservoir combo presumably with a specified in/out port.

Dumphole · 3 Sep 2016 at 21:57

That's great, thank you for your time!

Dumphole · 4 Sep 2016 at 10:35

Cool beans, I should have all the parts by Wednesday so hopefully it'll be sorted shortly after then!

Dumphole · 5 Sep 2016 at 15:03

Ha! I know what you're saying. I've made a start already though by fitting one water block (I'm only using the other 1080 atm, tough life...!) and I've fitted the front rad and fans. I'll have it done by the weekend for sure. I'll post a pic and some benchmark temp tests on here once sorted. Its a functional build rather than cosmetic though. The only concession to looks I've made are some big chunky 19mm tubing (I like the Scan 3XS wc builds which use big tubing) and uv green coolant.

Here's where I'm at.

I had a leak early on which gave the top gpu a slight bath. I know this means stripping it down, I'm building up to that!

It seams that adding a front rad destroys any hope of using the cases built in or accessory pump mounts so I had to make a new mounting plate which I painted and has turned out very well.

The psu fan is louder than the pump, I'm amazed at the rate at which it flows too,very pleased.

I'll stick another pickup once it's all working again.

I've been playing Siege for about an hour now and I'm getting about 55oC under load across all components. This is actually a decline in performance for the cpu. The H110 I had before did a better job with that.

The 1080's are juuuuust starting to adjust their oc as they get to mid 50's.

Well it's always been an sli and 6700k setup just with fe blower coolers and an h110. There's still some tweaking needed and I did go for the cheapest radiators I could! My reason was aio coolers use budget radiators and cool fantastically so these being of a similar quality should function just as well.

Dumphole · 9 Sep 2016 at 08:28

With the system fans set to max I can keep temps at or below 55oC. I'm going to try flushing bleeding the system some more I think to see if there is any air trapped anywhere preventing use of the radiators full surface area. I might also replace the top 360 rad with something much thicker.

Dumphole · 12 Sep 2016 at 19:24

It'll probably fit on its own or maybe with using a 240mm front rad. I've used a 280mm front rad and now I cannot fit a thicker 360 in there at all.

I'll take a pic tomorrow and post it up.

Ref my setup I've ordered some better fans for the 360mm rad. The current setup has the fans above the rad pulling air through however, its weak without much oomph to the air flow. They wouldn't fit on the push side as they hit the fittings. I plan to trim some cut outs in the fan housing to clear the fittings in order to fit them on the push side. I thought I may as well upgrade them to some F3 Vardars whilst I'm at it.

Dumphole · 12 Sep 2016 at 22:16

I'll struggle with that as I can't filter the top radiator/fans.

Dumphole · 13 Sep 2016 at 00:19

I'll have a fiddle. The top rad is on a slide out tray. Access above that is impossible with the tray in place and I'd need some much longer top rad hoses to allow wiggle room. I'll have a play and see what I an come up with.

Rad clearance.

Dumphole · 13 Sep 2016 at 08:55

I like that idea, I'll get a filter and give it a try. Thanks guys!

Dumphole · 13 Sep 2016 at 23:59

I've just seen peaks of 67c on the gpu's! Cpu doesn't go into the 60's though, ever.

Dumphole · 14 Sep 2016 at 19:41

That's frustrating. I've no idea why I'm seeing such drastically different temps.

I'm going to change the exhaust to inlet, change the top fans for something with balls and re-mount all the blocks with artic paste. If that doesn't do it I'll just not look at the temps anymore!

Dumphole · 15 Sep 2016 at 17:11

I fitted some f3 vardars to the top rad pushing air through the rad and out the top.tgey definitely changed things as it took a lot longer for the cup to heat up but temps are still high.

I disabled sli next to see temps on a single gpu but guess what,still hitting the 60's...

Dumphole · 15 Sep 2016 at 20:10

Well, running all three oc'd or at stock speeds makes no difference. Fan speed, makes no difference. Pump speed is roughly 3100rpm and as far as I know is not adjustable. I ran the rear fan as an inlet but that made no difference. Maybe 1080's are just hot?

Dumphole · 15 Sep 2016 at 21:11

Well, the vardars are considerably more powerful than the Akasas in there previously and pushing air. I can actually feel air exhausting from the top panel vents now. The remaining fans are the original Phanteks 140mm static pressure jobbies. They seem OK.

I've just swap the gpu water feed to parallel instead of in series and I'm currently bleeding it again. I may get some 140 vardars in place of the Phanteks fans. I may even squeeze a thicker 280 front rad too.

Dumphole · 15 Sep 2016 at 22:20

So parallel made no difference. They're equally hot now!!!
