My watercooled Lian Li PC-70 project
Page 2
(more or less) Chronological pictures of the project:
A general view of my Lian Li PC-70. All hoses are 1/2" silicon tubing and
are fixed with hose clamps.
All PVC parts have an ID of 20mm (a little more than 3/4"), the copper
tube is 15mm OD (a little more than 1/2").
The radiator is the new AquaCoil II with two 3/8" parallel waterways and
1/2" connections.
AquaCoil II radiator & Enermax 550W. I drilled the rivets of the L-shaped
alu plate near and beneath the PSU. Than I removed a part to clear the radiator
(on the left) and for the 92mm fan of the Enermax (at the bottom).
View from the other side + Panaflo L1A fan.
Between the Panaflo and the AquaCoil radiator I mounted an aluminium (1mm
anodized) shroud of about 2.5cm (1") so that I could mount the Panaflo on
the other side of the radiator (sucking air instead of blowing), and so that
the Panaflo is 1.5" away from the cooling fins.
The hole for the 92mm fan of the Enermax + modded Swiftech. I inversed the two
rear 80mm fans so that they blow air into the case together with the two front
fans. Input is now about 124CFM (4x 31CFM) and Output (Enermax + 120mm Panaflo
L1A (69CFM)) is about 100CFM, so that I have a little positive pressure in the
case.
This is not a reservoir but an "airtrap" at almost the highest point
of the system to "trap" or bleed remaining air bubbles in the water,
and also to have a visual indication of the water level. Since the upper cover
is removable I can add water to the circuit.
The PVC-part is made of 50mm OD PVC (2") and two hermetic endcaps with a
screwed cover of 50mm + about 15cm (6") plexi tube of also 50mm diameter.
On the T-part is mounted two brass adaptors (1/2" to 15mm) to connect to
the 15mm copper tube.
The 90° copper turns are hardsoldered to the brass adaptors.
Sicce Idra 1300 liter/hour pump (320gallon/hour) + bleeding & filling
system with Eheim taps (petshop).
The big tap has a 3/8" thread and is screwed to the PVC via 1/2" to
3/8" brass adaptors with Teflon.
The two little taps (1/4" thread) are screwed with Teflon via 1/4" to
1/2" brass adaptors. Everything is screwed to the chassis via the two 27mm
clamps. All PVC parts have an ID of 20mm.
Between the PVC-part and the pump is a little piece (4cm) of 20mm silicone tube
to prevent vibrations from the pump to pass to the chassis. The pump itself is
mounted on rubber suckers.
The two little taps are used to fill and bleed the system (via 3/8"
silicone tube to a "jerrycan" with cooling fluid).
All PVC is glued with "hardPVC" glue.
The rear side of the PC-70.
The front side.
The new "PSU mounting plate" with Panaflo L1A. I made it using the
original mounting plate as a model + the additional hole for the Panaflo. I had
to rotate the hole for the PSU because originally the PSU is mounted with the
92mm fan upwards. Beneath the Panaflo is the AC connection and switch for the
waterpump.
"Spoilers" near the fans to prevent the two 80mm fans to suck in hot
air from the PSU and the Panaflo (I smoked a lot of sigarets just to see where
the airflow of the fans was going).
