Features [ Edit | History ]


New bracketry included as of 9-1-06

NEW: Effective August 30, 2006 the MCRes-Micro is shipped with a set of adjustable brackets to further facilitate installation of the product. See examples of installation below.


The patent pending MCRES-MICRO is a small form factor reservoir designed to operate quietly and reliably with high flow pumps such as Swiftech's MCP350 and MCP655 models (3/8" and 1/2" lines). The patent pending design features an angled baffle forcing the turbulent flow at the bottom of the reservoir. This allows it to function without air entrainment at low fluid levels and affords extended usage without refills for approximately 2 years.

Features & Benefits

Small size: 4 x 3 x 1.5" (100x76x38mm) Can be installed in most systems including many small form factor cases without sacrificing a CD-ROM bay.
Separated from the pump Can fit in smaller spaces than integrated pump/reservoir setups.
Anchoring ears, and velcro pads Easy to install against case panels, either with the supplied velcro pads, or permanently with screws.
NEW! Adjustable brackets Greatly facilitate installation and are adjustable in all 3 axis.
Specially designed for high-flow pumps No annoying sloshing sounds and completely free of any air entrainment even at the lowest possible operating levels.
Patent pending baffle design Approximately 24 month of continuous operations without refills (*) in 3/8" systems, and 18 months in 1/2" systems.
Cosmetic appeal Transparent acrylic panel construction.
Built-in reliability Stress related cracks found in other acrylic constructions is eliminated by design: straight NPSM threads do not induce stress compared to NPT (tapered) threads.
1/2" and 3/8" barbs included Universal use with high flow systems.
Fill-port cap and NPSM barb fittings use O-ring Highest reliability thanks to O-ring seal.

(*) Refills are necessary to compensate for the evaporation of the fluid through vinyl lines which are slightly porous. The above specifications are estimated from actual tests performed for a duration of 10 months, with a system composed of MCW6000 waterblock, MCR120 radiator and MCP350 pump, 6 feet of 3/8" vinyl tubing, and operating 24x7.

Experience: 2 Weeks

Verified OwnerVerified Owner


compact size
turbulance dampner
looks nice
easy to mount/find space for
Cons plastic barbs included ... why bother


Its a res , it holds water does what it should does it great.
Bleeds system fast, mounts easy and is compact enough to find room anywhere. Easy to fill. Nice look. Turbulance dampner is great and can see it doing its job , will deff help fight cavitation from occuring here.

Downside: plastic barbs included with this , id like to see metal ones but would prolly drive up the price , but i mean come on plastic why even bother.... would have gotten a perfect 5 from me if this issue wasnt there.

Cons none


Whiles marked at such a low price, this res performs great. Bleeds system in a matter of a second. If you go water cooling, you got to get this.

Experience: 2 Weeks

Cheap, good design (eliminates vortexes), looks good
Cons The top fillport is some stupid threaded design and is NOT G1/4 so you can't just put another barb fitting, you have to retap it with 1/4 NPT


I actually attached this with two zipties through the rear mounting holes and is holding it relatively straight. Its a cheap res and it performs the job admirably, the only reason this is getting 4 and not 5 is that the top fillport has been threaded with a outdated thread type and there is NO reason whatsoever that it couldn't be 1/4" NPT like the two ports.

Here's a tip: get a 1/4" NPT tap and just rethread it. Then you can attach your barb fittings.

Very easy to bleed the system
Better then Intergrated res on a rad as you can actually see the levels of the liquid.
Holds a lot of liquid surprisingly bigger then i imagined.
Cons I didnt like the mounting mechanism had a bit of difficulty but used some zipties to secure it to my Cosmos S case


Works well and awesome took only a few minutes to get all the bubbles out of my system a lot easier then my previous system would defitnetely buy again! Good work Swiftech.

Experience: 30 Days


Straight cut threads for the hose barb fittings. These things seal using an O-ring(You NEVER want to use pipe thread on plastic because pipe thread is TAPERED, and will easily crack the plastic while tightening to get a good seal).
Cons The plastic hose barb threads are too long for the reservoir wall thickness, so the top barb hits the underside of the baffle. You either cut it back, or install the D-Tech G1/4 high-flow chrome barbs which fit perfectly.


The internal baffle works very well, so there's NO air entrainment from the reservoir. My system bled all the air out within 1/2 hour, including those fine, frothy little bubbles that hardly make any noise going through the pump.

The walls are clear enough to see through, so if anything starts growing in your cooling fluid you'll see it right away.

The fill port is installed in a well to catch minor spills.

Great Build, Comes with everything needed
Cons Plastic barbs


It's very sturdy but it's a bit on the small side. It looks great and the barbs that come with it are ok. But they are plastic so you might want to change them.

Experience: 30 Days

Cheap, small, well built
Cons none


This res is great for the price. It small so it can fit almost anywhere in your case. It also comes with mounting hardware to make it easy for you to do so.

Experience: 2 Weeks

-small size
-ease of use (bleeding)
-chic design
-multiple easy mounting options
Cons -small size
-plastic barbs


what's more to say about this product that hasn't already been said? it's a fantastic reservoir. it's incredibly easy to use. you can get quite creative, due to the included mounting hardware, in how you would like to display it without resorting to direct modding. if you are new, or a vet, to liquid cooling, i highly recommend this product. it would have been nice if the kit included chrome barbs, but then again, that would have increased the very reasonable price.

Good build quality, sturdy. Multiple fittings, comes with many ways to attach it.
Cons It can be a little hard to mount
The mounting hardware is too much of a hassle IMHO


It is a good basic resevoir, I dont know what else you would want for $20, comes with all the fittings, and different ways to hold it in place including Velcro
