Thermaltake SR200 Liquid Reservoir with P500 Pump

Thermaltake SR200 Liquid Reservoir with P500 Pump

A few days ago I purchased the Thermaltake SR200 Liquid Reservoir with P500 Pump pictured above. I thought it would be an upgrade for my original water cooling setup. While the new hardware has some benefits it’s not really a massive upgrade in my opinion. There are a few features that make it better than my Thermaltake ProWater 850i Liquid Cooling System. But one key piece of the new equipment is a slight downgrade. Honestly I didn’t compare reservoir capacity numbers when I made my purchase. This new model looked to have a larger reservoir than what came with the ProWater 850i. When I received the new hardware on Monday and compared them side by side the two containers visually seemed like they would hold the same amount of liquid. I reviewed the actual numbers tonight and found the new reservoir has less capacity. It’s a difference between 225cc and 350cc. So the older liquid container actually held more than what I just upgraded to. Of course this is my fault for not checking numbers. Part of the reason I wanted to upgrade was for more coolant storage.

From what I have read a larger reservoir helps to dissipate heat more effectively. I had hoped to use the old container as a second reservoir. That didn’t work once I took my setup apart and looked at the parts. There is no way to use the ProWater 850i liquid box in the current system do to it’s design. Basically there isn’t a way to connect hose to the bottom outlet. So I’m stuck using the SR200 Liquid Reservoir only.

The 850i and SR200 share the same liquid pump. So you aren’t getting an upgrade there. Both sites I use to buy hardware didn’t offer the reservoir alone. One site didn’t even have the Thermaltake SR200 for sale. You might be thinking is there any real value in purchasing this “upgrade”. Thermaltake markets this as an upgrade for the Thermaltake ProWater 850i Liquid Cooling System. While I would question how much of an upgrade this is. There is value in the SR200. The reservoir looks nicer. You get a metal bottom and screw on top. Compared to the all plastic 850i reservoir I like this one better. One major problem solver is the adjustable hose connector. This allows for a much easier process of running tubes inside of the case. It also reduces an type of kink you might get in the hose. I’m not sure why Thermaltake hasn’t had this simple but useful hardware setup in the past. All of their water cooling kits should include this.

When installing this model keep in mind the reservoir is vertical. If you have a small case it might cause clearance issues. I have an older Thermaltake Tsunami Dream case that works well with the SR200. Previously with the 850i I was dealing with a square box instead of a round cylinder. The way theĀ  SR200 Liquid Reservoir was designed has the liquid slightly bubbling when coming into the container. This is do to the fluids being forced up instead of down. I’m not sure if this has some benefit in regards to cooling. It’s not a bubbling really just more of a movement do to pressure I guess.

I’m not completely unhappy with my purchase. It looks better than the previous model. The clear reservoir with the SR200 is much better than the dark plastic one that comes with the 850i. It’s now much easier to see how much fluid is in the container. This wasn’t an easy task previously. Current system temperatures with the machine overclocked are within very reasonable levels. Of course this time of year my area has the need for heat inside our homes. So cooling performance will be tested more during this season.

My previous overclocking temps were less than stellar with my old setup. I’m thinking some of the hose rerouting I’ve done has helped resolve that. Only a full review after the winter season will show if that holds true. I’ve only been running the new hardware for two days – things could change. This setup is cooling the processor and two hard drives. At the moment all the hardware is close in running temperatures. Meaning one component is not cooler than the other. All are close to equal. The old setup cooled the same hardware. But I think there may have been just a bit more temp variance.

My lowest temperature I’ve seen on boot-up this year has been 17c. That was last month with the previous setup.
