PETG hardline
Easy to heat and bend, with enough tolerance for a first hardline water cooling project.
BEST FOR / measured routes and strong colour
Custom water cooling Sheffield / build brief 06
Engineering meets art.
Your PC runs well. You want it to look like the centrepiece of your setup and run even cooler. Blackwell's Builds plans and installs hardline water cooling, custom cables and themed details around the parts you actually own.
Hardline loops. Clean routes. No accidental clashes.

LOOP / ROUTE / TEST
01 / system architecture
Loop planning: compatibility first, beauty second.
A clean loop starts before the first tube is cut. We check your case, GPU block, CPU block, radiator clearance and drain access, then map the shortest sensible route.
Small details prevent expensive rework.
Compatibility matrix
Checked before parts are ordered
| Component | Block | Radiator | Drain |
|---|---|---|---|
| Case / chassis | PASS | PASS | PASS |
| Graphics card | PASS | CHECK | PASS |
| CPU socket | PASS | PASS | PASS |
| Fittings / metals | PASS | CHECK | PASS |
The route we draw
- 01 Pump to GPU block
- 02 GPU to CPU block
- 03 CPU to radiator
- 04 Radiator to reservoir
Copper and nickel stay compatible. Mixed metals stay out.
02 / material selection
Hardline, soft tube, and coolant choices.
The right material depends on access, maintenance and the look you want.
Acrylic hardline
Clearer under lighting and more resistant to heat, though it needs precise cuts and careful bends.
BEST FOR / presentation builds with exact geometry
Soft tube + coolant
EPDM or PVC makes maintenance simpler. Clear coolant with coloured tubes keeps the service routine sensible.
BEST FOR / stealth builds and regular upgrades
03 / internal finish
Cable management that disappears.
Custom-length sleeved cables keep the PSU, GPU, motherboard and EPS routes tight. Combs hold each run in line while the rear panel stays serviceable.
Airflow improves when the clutter leaves.
Discuss your layoutBEFORE / LOOSE RUNS
Long excess. Blocked intake.
AFTER / MEASURED ROUTES
Short runs. Clear channels.
04 / visual direction
RGB or total blackout: your choice.
The lighting plan follows the room, the desk and the parts. Motherboard sync can run through ASUS Aura or MSI Mystic Light. A blackout PC build can hide every logo and leave only the shape of the machine.
RGB showcase
Colour-matched coolant, controlled zones and cable sleeves that support the palette. The light has a job.
OLIVE ICE PLUM
Blackout build
All-black components, hidden branding and subtle grey accents. This is for a quiet, architectural desk setup.
MATTE GREY LOW KEY
Themed builds can take a harder turn.
Cyberpunk panels, retro hardware cues, nature tones or team colours all begin with a written palette and a parts list.

Your dream build starts with a conversation.
Let's plan your centrepiece. Blackwell's Builds leak-tests hardline loops for 24 hours, then gives you a maintenance routine you can actually follow.
