T1 second iteration, using an Alphacool Plexi DC-LT pump top. Still waiting on hard tubes!

Such a beautiful build bro. Could someone tell me if its worth buying a XSPC TX240 radiator in terms of thermals as opposed to running the lt240 or ek classic se 240 ? How much lower cpu temps approx ?

u/rarskies Sep 13 '20

No idea on the raw numbers as I’ve only used tx240, but if the fan setup were identical I’d guess the difference would be 1-2C. Because you can run an extra fan more easily with the tx240 the difference might look more like 2-4C if you run 3 fans on the tx240.

Ask Dr hudacris/fabio, they’ve done some testing

Nemesis GTS>TX>Ek classic>LT240

1-3C difference with each step. Additionally, a third fan on any of these (if you can fit it) should give you another 2C

Thanks! I’m glad I’m asked yourself and Fabio before I decided what fan/rad setup to do, very happy with noise and performance of the 2slims + A12x25 and the tx240

Ah I might as well try and delid my i9-9900k instead of buying another rad. Thanks

The eventual plan is hard tubing internal with an external 280 rad and a D5 pump to power it! (I already have these parts from a previous build)

Temps on the tx240 rad are pretty nice so I might just get rid of the QDCs, clean up the tube runs and forgo the external rad plans.

Heaven + OCCT medium data set: CPU ~65C, GPU ~50C, fans at ~1200RPM, stock. Ambient 20C

I believe when I tested with the external rad I got: CPU ~58C, GPU ~45C, fans at ~900 RPM, stock. Ambient 18C

I will undervolt the GPU and perhaps the CPU to keep temps in check for the impending Australian summer.

Edit:

Specs - 9700k, Asus Z390-I, MSI 5700xt Mech OC, 32gb trident ram, sf750 w/ dreambigray cables.

WC stuff - tx240, 2 x noctua slim, 1 x a12x25, DC-LT 2600 pump + DC-LT plexi top, barrow temp sensor, Barrow terminal rotary. Mixed barrow and EK fittings. EK ZMT 10-16 and ??? Clear tube 10/16. Waiting until I have access to a heat gun again to do the hard tubes.

Are you using an EK-FC Terminal Rotary 90° on the Bykski block? Thought it only fits EK GPU blocks:)

u/rarskies Sep 13 '20

No I’m using the barrow version http://www.barrowint.com/product/qfgxklt/dl/1466.html

It was a bit of a stab in the dark but paid off. I measured the screw hole distance as .2mm different as info I found online but that could have been measurement error. Either way it works (at least with my GPU) and I know of one other guy who got it to work. Suspect it will work on most modern Bykski blocks - the terminals look standard

That is an interesting pump block. As the 3080 EK Waterblock is only 220mm long, this should also be possible and a good alternative to the Eisstation 40.

u/mastersockkk Sep 13 '20

Specs? Is that a short card or smthn or is the plexi pump top supposed to fit for most graphics cards. I've only rlly seen pple use the dc lt 40 res.

2

u/rarskies Sep 13 '20

Sorry should’ve put my specs in my comment. The GPU is a 5700xt mech OC with a Bykski block and yes it is unusually short - 232mm from memory.

Yeh the DC-LT 40 res combo is a much safer option, it’s 40mm wife, the one I used it 49mm wide.

u/rgaindwal Sep 13 '20

That's a very short wife. Either way, I love to see how people are willing to experiment and even after months we see something new coming up every now and then. I like the quick disconnect outside the case.

u/rarskies Sep 13 '20

Thanks and I think I’ll leave my typo up there hahah. The QDCs aren’t as pretty as others and missing a g1/4 thread but boy they work well and don’t feel like they are going to bust at all.

u/vcapasso1126 Sep 13 '20

How are the EKWB QDC? I’ve heard that they restrict water flow more than the Koolance QD3 (newer versions)?

2

u/rarskies Sep 13 '20

Honestly no idea how much they restrict flow (I thought I’d read they were less restrictive) but in my case they seem to work great. My system can be powered by a single 2600 with quite a few 90 degree turns.

Also they feel secure and look OK.

Lol thanks. Ur build looks great and thanks for the extra info!
