Water cooled mining review Part 1

How did YOU start mining?
Well for me it was just after I had build my first water cooled gaming rig. I was playing in my mind with the idea of a water cooled PC for years and 2017 was the year I finally had the funds, the time and bravery to spend over 5000$ on it. The project took me around 6 months to complete and 3 full days to build to the point when I was able to make a picture of it that was looking good in my eyes.

Specs of the rig:
MB: Gigabyte Ultra Gaming x99
CPU: Intel 5820K
GPU: 2 x ASUS 1080Ti Founders Edition
PSU: EVGA 1000 T2
RAM: Corsair 32GB 2400Mhz DDR4
Case: Phanteks ENTHOO EVOLV ATX GLASS
M.2: Samsung SM961 256GB
SSD: Samsung EVO 850 1TB

Water Cooling specs:
Rads: 2 x EK-CoolStream CE 280 (Dual)
Fans: 5 x Phanteks 140mm case fans
Pump/Res: EK-XRES 140 Revo D5 PWM (incl. pump)
Fittings: EK-HDC Fitting 12mm
Tubes: EK PEGT
Coolant: Mayhems Pastel Red
MB Block: EK Monoblock for Gigabyte X99
GPU Block: 2 x EK Full Nickel Block with back plate

Case mods:
Front cover: 5mm space increase in air intakes
Top cover: Laser cut to improve air exhaust

So after spending few hours (124h) playing the latest part of my childhood favorite game (Fallout4), searching for aliens, folding at home and brute-forcing my neighbors WPA2 WiFi password, I decided to give mining a try with those two 1080Ti cards.

Here are the Pros and Cons I can share after mining 24/7 for the last 5 month on my gaming rig.

Pros:
Thermals – Well that’s obvious. Mining on a water cooled rig gives you a superior way to remove thermal stress from your mining cards.
Overclock Stability – You will be able to push and keep your cards at a higher overclock speeds.
No fans on cards – you don’t have to set any fan profiles on your video cards. This means that if your overclocking software fails, your cards will not burn up.

Cons:
Pump stress – you stress your pump 24/7 and this will wear it off faster.
Coolant stress – your coolant will change color faster. Especially if you are running a red pastel like me.
Number of cards – if you are going to mine with your regular water cooled gaming PC, then having 8 cards will not be possible.
Movement of hardware – if you have issues with your cards and you want to change one, or just exchange the places of your cards, you will have to drain the system.

So if you are considering mining with your water cooled rig, you will have to choose a solid pump and coolant that is not going to degrade fast. In Part 2 I’ll show how does the Mayhems Pastel Red become the color of poo, and compare cooling performance and hashing speeds with the new PrimoChill Vue.
