Thermaltake Pacific DIY PR22-Ddc 300ml 4600 RPM 3-Port G 1/4" Thread PPS Pmma Ddc Pump/Reservoir Combo CL-W250-PL00BL-A

The reservoir is watertight, assuming you make the connections properly, and the pump is quiet on its highest setting. That's the most important things to me. The inlet tube makes sure air trapped at the top of the reservoir doesn't get entrained into the water flow and circulated out into the system. It's a common feature on reservoirs, but some don't have a long enough tube. The mounting is a little clunky, I mount it to the floor of the case and I don't need the vertical mount bracket sticking out the back and making it look part finished. The pump wiring is long and colorful, which doesn't go with the black wiring on the cap. The pump/reservoir comes with a USB hub with another Molex connector, seems like they could have done something to reduce the wiring. It also comes with a micro USB cable for connecting to the motherboard. Fortunately my motherboard has plenty of USB connectors, and I don't need any of the conventional USB headers, so this wasn't a problem. In my case the pump drives water through two water blocks, two large radiators, and an inline mesh filter rapidly enough to keep the exit temperatures from the water blocks down to 10C over ambient. If I need another reservoir/pump this would be high on my list. I bought it on sale, so it was an easier choice at that time.

First, I'll say I do not like Thermaltake. Their software for the RGB is annoying. With that being said, their hardware is exceptional. I have been building PC's and using Thermaltake products for many years. This pump in particular has been in two different builds over the past year and half. It runs strong, is super quiet, and I can trust that it is going to last a long time. In the current machine it is pumping through 2 360mm radiators and no problem with flow.

They work pretty good, i will say, they dont seem to work as well as my EK D5's and have no way to adjust the speed/flow (EK ones did). For the price, they are great. They make water move from A to B. Now, the downside is the massive lack in design forward thinking. There is 1 port on the bottom, 2 on the top. Unless you are adding a split (Y ot T) for drainage, there is no train port on these. Dumb. Total lack of forward thinking in the design. I dont want a massive T/Y splitter on my lines for drainage because all those extra parts cost A LOT. Do i want to burn 4-6 MORE parts to connect random lines that really shouldnt need to be there? No, no i dont. As for the RGB, its ok at best. Lots of little design lighting but in the end, the single LEDS are terrible. Maybe if you are using some pastel color stuff, but, in the end, its not effective. The full colors are great, sound detection is OK at best. Barely lights up, again, using a single LED doesnt even show up so why do it? There is nothing really subtle about the lighting ... just lack of lighting lol. They are ok, nothing great, nothing bad, its a solid "meh".

Excellent build quality and operation. Non PWM so you'll have to manually set the desired pump rpm. Kind of tall so it fills in a bit of that unused space. Just beware that the pump speed selector is located on the bottom of the assembly and that could make it tough to change rpm. Flows great, runs quiet. Very happy with it so far.

Pros:1. Nice looking, be sure to add at least 80% to reservoir.It’s very quiet when it doesn’t have to work hard so make sure once again that you have added about 80% to the reservoir. **** I can’t stress this enough. If you turn the pump on and water is still being sucked down the reservoir it isn’t quite full yet**** it’s loud when it needs coolant but quiet when it doesn’t.2. My configuration: I added a bitspower T-valve to my outlet port at the bottom, straight off the pump. This is working great. I let it bleed for 24 hours with the fill port open to remove bubbles.Cons:1. The instructions are horrible. I have the plus model. I still don’t know how to use the RGB cap, theirs a controller and a whole bunch of cables that made my head hurt. If I figure it out I’ll update on how I got mine working.2. I’m coming from a EKWB kit and the only reason I can’t use that one is because the case Thermaltake 900 doesn’t have holes pre-drilled for other reservoir/combos but their own.3. No header controls. This is running off a molex connection from your power supply. Be sure to use a jumper to do testing. Not necessary but be efficient.4. I don’t believe the lid comes off on the Plus RGB model. I could be wrong but I didn’t risk forcefully taking it offTip: if you get some leakage near the outlet port and you have a drain valve running on it, tighten it the best you can with some gripped pliers if possible. You should see your o-ring at all.Update(05/12/2020): I set my pump to 5-speed.My radiator is a 240mm CoolstreamUPDATE: Stopped after a year. Loud grinding noise and now I think it might have burnt up my CPU. I’m deeply saddened.

I think the product works great for water flow. The problem I have is that the RGB went out after around 3 years of use. I don't know if that's the normal operating life for it, but for the amount of money I paid I would expect it to last much longer than that. I have 2 pumps that I've purchased and used and the RGB went out on both within days apart after just under 2 years. The pump is still flowing strong so I don't think it's feasible to spend another $400 for 2 pumps just for RGB Lighting. Bummer that the RGB isn't replaceable in itself. They are very silent which is nice as well. I don't like that the only speed control it has is on the bottom of the unit. Once you install it, you might as well kiss that feature goodbye because you can't access it usually once it's installed. At 300 ml it has the capacity to cool multiple units and i'm sure it will do it well. I also wish it had an extra port on the bottom for drainage. That's just poor design on Thermaltake's part.
