TT Tower 900

Hello everyone,

I thought I would share some pics with the start of a Thermaltake Tower 900 build. I chose this case because it supports two 560mm radiators and two pumps/reservoirs for two liquid cooling loops. What I'm after is silent, high performance cooling.

Case - Thermaltake Tower 900
Motherboard - ROG Strix Z690-F Gaming WiFi
CPU - i7 12700KF
Memory - Kingston Fury Beast 16GB 6000MT/s
GPU - ROG Strix 3090 Ti LC OC
SSD - Seagate Firecuda 530 1TB
Fan controller - Lamptron FC5-V3
Case fans - 2x Gelid Solutions Wing 14 uv Blue in the front and 2x stock 140mm fans in the rear
PSU - EVGA Supernova 1600w T2 Titanium

Water cooling:

Fittings - EK Quantum Torque STC 10/16mm (3/8 x 5/8)
CPU water block - EK Quantum velocity2
GPU water block (soon to come) - EK Quantum Vector2 ABP set
Pump/Res - 2x Swiftech Maelstrom X300 D5 V2
Radiators - 2x Hardware Labs SR2 560 MP
Radiator fans - 8x Thermaltake Ring 14 Blue
Tubing - Koolance uv/clear 3/8 x 5/8 soft tubing
Coolant - Koolance 702 uv blue
Temperature sensors - 2x Alphacool Eiszapfen flat stop plug sensors- chrome

I like how the Tower 900 is laid out with the hardware in the front and the radiators in the back, there are three glass panels to see in the front and both sides. But, I have two cons with this case.

1) It's Big, it's Bulky and it's Heavy. Empty it weighs 54 pounds, by the time it's built expect it to weigh 100 pounds.

2) Airflow - This case is meant for liquid cooling EVERYTHING and the front does not offer proper airflow, you get one exhaust fan above the motherboard and a hard drive fan mount in the center of the case. The vents at the bottom allow cool air to be drawn in.

Other than that, it's a solid well built pc case.

As I'm waiting to get a few more things, I went ahead and made a few changes. I took the two stock 140mm fans and put them on the back panel as exhaust and added two 140mm uv blue fans. There are no hard drives, it's just to help move air and hopefully give off a uv glow.

I flushed the radiators with hot distilled water, I didn't use any chemicals such as Mayems blitz or vinegar. The one radiator took 40 flushes, yes 40, until absolutely nothing came out. If I saw one particle it got it again, the other radiator took only 10 flushes.

A tip about the HWL radiators - I don't know if this holds true with all their radiators but the screws HWL provide with the SR2 560 MP are not long enough to use with a mounting bracket, you'll need to purchase 4x30mm screws to use a mounting bracket.

The Tower 900 comes with pump/reservoir mounting brackets for Thermaltake's pumps/reservoirs and they didn't match up with the Swiftech Maelstrom pump/res combos.

93473

So out came their mounting brackets and I drilled holes in the bottom of the case to mount them, but I ran into an issue here too. The Swiftech mounting brackets are too wide, I had to make four cuts to get them to fit flush on the bottom.

Two cuts for each pump/res, this is one.

After that, they test fit nicely.

More to come.

This worked out pretty good, I really like these EK Quantum Torque drain valves. With a test fit, the drain valves are short enough to not hit the dust cover.

Would I need two drains in each radiator or is one sufficient?

I think so too ahfoo !

The Hardware Labs SR2 560 MP are multiport radiators, 8 ports total. I would have liked to have seen them use metal stop fittings for the unused ports but they used POM or plastic ones. I'm going to install a temp sensor below the outlet port of each radiator, install an EK Quantum Torque drain valve in each, then install some metal stop fittings.

Swiftech decided to use their own 3-pin ARGB connector. To connect the pump/res combos to the motherboard and control them with Amoury Crate, I need the Swiftech Iris MB Link which will be here today.

Since most of the wiring will be done, I'll install the radiators and Thermaltake fans. The fans will be controlled with the Lamptron FC5-V3 fan controller, the temp sensors will also connect to the fan controller.

Looks good Nate, awesome build! :cool:

I've got (9) of those HWL SR2 Multiport badboys, I LOVE those rads. It's a shame I'm only currently using one out of nine. lol

Guess I'll sell the other (8)... 🙂

If you want an inaudible airtight seal fans to HWL rads go with the AlphaCool Phobya 140mm fan gaskets, cut to fit. Cheers!

Up until now things were going pretty smooth but I have a gripe and is worth mentioning again.

I don't know who is at fault, either Hardware Labs put 4x28mm screws in their 4x30mm packages or Performance Pc's grabbed the wrong ones off their shelf but the 4x30mm screws I purchased are the same exact size that came with the radiators which are 4x28mm. So these screws are also too short. I don't know how else they would expect us to use their radiators other than mounting them into a case with a mounting bracket.

According to reviews, Hardware Labs radiators are up there near the top as far as build quality and cooling performance goes. But, the too short of screws and plastic stop plugs makes me give two little strikes against them.

Ok, gripe over as I was able to mount the radiators, I had to remove the blue antivibration tabs, this then made the screws long enough. There was some white glue left behind I painted over black.

So all in all, all black fans doesn't look too bad. After getting the radiators in there, the EK Quantum Torque 90 degree rotary fittings worked well, I'll need two more.

The coolant is uv blue, the tubing is clear/uv blue so I'll need uv lighting.

I got four Darkside dimmable 12" uv led strips, two are extensions. I'll shorten the distance between the two connections with a loop or two and a zip tie, at least that's my plan as they have to be no longer than 26".

I added a Darkside 3-pin fan cable (Type 1s) to connect and control them with the Lamptron fan controller. I could get a splitter to control both strips with one channel but there's enough channels to give them each a channel.

I wish they were magnetic.

I was able to shorten them up and install them in the front part of the case frame, there is a strip on each side.

For the best results the led's should be hidden.

Cpu loop is done

Sometimes things don't always go as planned. After seeing the tubing from the cpu water block through the cutouts, it was too loopy. I added two EK Quantum Torque 90 degree rotary fittings, this looks better.

Just missing the ram sticks.

I wanted a drain valve at the pump/res's too. What I did was used a male to male extender, a T and a Quantum Torque fitting on the end. I put a Quantum Torque 90 degree rotary at the T and connected the drain valve to it. Because it's rotary I can swivel it a little if I need too. These EK Quantum Torque drain valves are nice, they're compact and can be used pretty much anywhere, they also have the G1/4 male threaded end and a screw cap.

The drain valves are black nickel, they look more nickel than black.

Unscrew the cap, connect your drain hose with a G/14 fitting, pull the drain valve to open and drain, when drained push to close, unscrew your fitting and hose, screw the cap back on and you're done. It doesn't get much easier than that for draining your loop.

Camera says I need to dust.

Bro, almost done, Can wait to see the complete setup.

While it looks pretty good in front, around back there are 0 places for cable management, nowhere to really hide the cables. So the best I can do is try to keep from blocking the radiators and psu fan as much as possible.
