Updated my system to run EVGA GTX 1070 FTW.
Did some other updates at the same time.
I had some trouble with the barrow 14mm hard line fittings. The ones I had are good when two pieces are fixed and the pipe cannot slip out. But the pipework going around my 5.25" rack was not like that. Two times as I was filling water and the D5 pump was at 100% power, a pipe would slip out and spill water all around. It was the pipe right after the pump. There was the most positive pressure, and that alone would push the pipe out. So I changed the fittings here to Barrow 14mm hardline compression fittings. They came in very cheap too! Here's a link: click
Just 15US$ for 8 pieces, with free international shipping.
You can pull the pipe out of this fitting too, but it very much more stiff. I trust these fittings for this kind of pipework and I do recommend them. The other fittings are also very good, but only in applications where the pipe cannot slip out.
GPU is now connected by 10/16mm tube. These fittings: click
I do believe these are the same as Alphacool's "Eiszapfen"
From left to right: 14mm hard line compression fitting, 16/10mm tube fitting, 14mm regular hard line fitting
Both 14mm fittings are equally deep, so I did not have to shorten any of the old tubes.
Also for the GPU, I bought a VRM cooling block. This one: click
The 10cm version. It's well machined, but the bottom surface is not polished to mirror shine. There's visible machining marks right there. For this application, I'd say it's quality is very good.
I did not remove the FTW card's heatspreader, which sits on top of the VRM FETs. Bonded the block by 3M double sided tape. This kind: click
I did not buy this stuff from Aliexpress - I had gotten it earlier from somewhere else.. The aliexpress link came to from google image search. That looks like the right kind. It's been there for just a couple of days, so who knows. Maybe the block will fall off after some time and I have to figure out something else
So FET's cooling goes like this: FET - Themal Pad - Heatspreader - 3M tape - Water Block. These FETs' thermal output is nowhere in the same ball park as GPU core's. The fets put out maybe 5 watts all together. It's enough that the heat spreader stays ~cool, and it seems to do so. I measured 40.03 degrees with my index finger
Here's a few bad pics of the GPU:
I've been able to squeeze 2114MHz from GPU and 9234MHz from the memory (Samsung).
Pushed the voltage bar in MSI afterburner to +100mV. The card runs at 1.031V. Wish for custom bios one day, as the Power% never goes above 90%.
My CPU is a i5 3570K@4800MHz
Here's my Fire Strike run:
And Heaven 4.0 run: click
