Hey All!

Just finished water cooling my mac. I haven't seen this done yet. The first custom loop in a Mac Pro without cutting or modding the case.

IMG_5254.jpg


Build Specs
Mac Pro 5,1 2012
Dual X5690
Gigabyte 5700XT Gaming OC with Byski Waterblock powerd via Pixlas Mod
Highpoint SSD7101A-1 - Raid Controller
2 TB Inland Premium NVME running Big Sur 11.2.3
2 TB WD Black SN750 NVME running Windows 10 via Opencore Legacy Patcher
Upgraded PCI, Intake, Exhaust and PSU fans to Noctua (Thanks for the help @KeesMacPro & @Stex)
Sonnet Allegro USB 3.0 PCIE card

Loop Info
Push/Pull Setup
"Push" - Noctua NF-A12-25 FLX connected to NA-SAC1 adapted
Radiator - BXQINLENX Copper 120MM
"Pull" - Removed PCI fan and replaced with Noctua NF-A12x25 FLX (Soldered proprietary Apple fan connector to retain SMC control)
Tubing - XSPC Clear 3/8 ID 5/8 OD
Pump/Res - Byski Mini DDC Pump/Res Combo
Coolant - Distilled water with biocide mix
Fittings - Barrow & Floratek fittings

Powered push fan and pump/res combo using these adapters - motherboard mini 6pin power -> Mini 6pin to 6pin -> Female 6pin to Female 6pin -> 6pin to Molex

I'm really happy with the turn out and was able to get my second x16 PCIE slot back thanks to the waterblock. Noticeable noise when running but not bad. Used primarily for gaming, music production, and light video editing. Still trying to figure out a way to bolt down the pump but heavy duty velcro is working pretty well for now.

Next mods I'm looking to do are clear vinyl side panel and add a Gigabyte Titan Ridge card to my free x4 slot.

Hope to see some more here for anyone daring enough to do so!

2023 Update:

Build Specs
Model: Mac Pro 5,1 2012
CPU: Dual X5690
RAM: 96GB (6 x 16GB) Samsung 2Rx4 PC3L-10600R 1333Mhz
PCIe Slot 1: GPU: Sonnet 6900XT with Bitspower Titan Series Waterblock powerd via Pixlas Mod
PCIe Slot 2: Highpoint SSD7101A-1 - Raid Controller
SSD 1: 2 TB Inland Premium NVME running Moneterey 12.6.3 via OpenCore Legacy Patcher
SSD 2: 2 TB WD Black SN750 NVME running Windows 10 via OCLP
SSD 3: 1 TB Inland Premium NVME macOS Extra Storage
SSD 4: 1 TB WD Black SN750 NVME Windows Game Drive
PCIe Slot 3: Sonnet Allegro USB 3.0 PCIE card
PCIe Slot 4: Gigabyte Titan Ridge
Fans: Upgraded PCIe, Intake, Exhaust and PSU fans to Noctua Fans
Power Connectors: Powered push fan and pump/res combo using these adapters - backplane mini 6pin power -> Mini 6pin to 6pin -> Female 6pin to Female 6pin -> 6pin to Molex

Loop Info
Push/Pull Setup
"Push" - Noctua NF-A12-25 FLX connected to NA-SAC1 adapter
Radiator - EKWB EK-CoolStream Classic SE 120 Slim Radiator
"Pull" - Removed PCI fan and replaced with Noctua NF-A12x25 FLX (Soldered proprietary Apple fan connector to retain SMC control)
Tubing - EKWB EK-DuraClear Soft Tubing, 9.5/15.9mm (3/8" ID, 5/8" OD)
Pump/Res - Byski Mini DDC Pump/Res Combo
Coolant - Mayhems XT-1 Nuke & Distilled Water Mix
Fittings - EK-Quantum Torque Fittings

This thing is a beast! Only downside is the CPU is starting to show its age with lack of AVX encoding and its starting to bottleneck when gaming a bit but I'm super happy with it so far and I wouldn't have been able to get any of it done without the help of this community. Next project will hopefully doing something similar with the Mac Pro 7,1!
