Swiftech MCR320-QP Quiet Power radiator

Pros: Great rad, nice and big and does the job. Keeps my overclocked PC running nice n' cool. I have 3 Antec tricool fans installed on this unit, all running at slow speed.

Cons: If you don't plan to place this rad in a housing, covering every surface with some kind of protection. The paint flakes/chips off very easily. Swiftech need to fix this problem.

Other Thoughts: Remember, this rad only needs fans that run at slow speeds. Any more, won't make any difference and just make a lot of noise.

Pros: Works great, cools efficiently. No leaks, built to last. 3 120mm fans fit nicely on them.

Cons: Paint wears or chips eventually (it has been three years since I bought them, late review I guess). Nothing to complain about though, all I could think of.

Other Thoughts: I use two in my 1/2" WC setup. One cools 3x480GTX and a 470GTX while another my CPU (i7-970) and MB (R3E, NB, SB, and some other components). They keep everything cool even while OC. One is on a radbox, works great. Never had a leak or problem. Swiftech WC components have always been good to me.

Pros: it carries water, cools it, and it lets air through it, but all in the right spots

Cons: could have higher heat flux, but that would get a lot louder

Other Thoughts: OK, the paint chipping problem will happen if you start bending the fins and bashing the frame, so don't do it

Pros: This is a great rad for the price you pay. Performs very well. No bent fins, all holes line up properly, great quality.

Cons: Only con like everyone else is that the paint does chip easily.

Other Thoughts: Bought this from another website. Received the new matte black version.

Pros: i was able to quickly rma

Cons: First of all, the thing leaked in 3 different spots when I powered up my loop.(def glad i mount rads outside of and behind the machines I build, or I would be out of a 2200$ rig.)
Secondly , the fan mounting holes were a mile off. Never mind they were tapped by a blind monkey.

Other Thoughts: Overall a terrible, cheap radiator. Poor construction is evident from the minute you open the box. Your fingernail could scratch the paint off, quite literally. I used to swear by swiftech, now I'm not so sure....think I'll try a fesser

Pros: Cooling ability is top notch for the price. You won't find another 3x120 with this kind of cooling power for this price point that doesn't require user modifications (heatercores and such).
Relatively low FPI (fins/inch) doesn't require 100+cfm fans to be effective.
Bleeds quicker than a BIX120.3 or BI GTS 120.2.
Zero problems with short-thread G1/4 Bitspower fittings.
The shroud is deeper than BI offerings, so additional spacers probably aren't crucial.

Cons: The finish chips/scratches easily... handle yours carefully.
The fan mount holes aren't tapped straight(perpendicular to surface), or evenly (holes lined up).
I had to retap mine (to 6/32).

Other Thoughts: I own several HW Labs rads and one first gen XS rad.
This is an excellent choice for a quieter setup without sacrificing cooling capacity.

Pros: Been using this with the radbox since Feb 08, no leaks, no problms. I have bottom 2 fans set to ~600rpms, and the top fan to turn on a nb chip temp of 38, and full rpms at 42, since the nb gives me a more "true-to-water-temp" reading, as the cpu bounces around between 33-42 depending on load (and water temp). If I turn all 3 fans to full, cpu and Nb will max out a 38-40c.

Cons: Very large, hard-ish to get my hdmi and dvi connected.

Other Thoughts: Did my first water change a few weeks ago, saw no signs of problems, will continue to use this same setup for the life of the computer.

Pros: Great fit, finish, and function. This radiator is designed for high airflow, the fin density is lower than others I have owned (eg Thermaltake) so there is less restriction to air flow at the expense of fin surface area. The balance between air flow and fin density functions very well. My system is very cool and stable, a big improvement over the 2X120mm setup I was previously using.

Cons: It is not a Feser, which cools ~10% more efficiently at double the cost. That's not really a con.

Other Thoughts: I will be purchasing another Swiftech 320 for a second loop. I really like this radiator.

Pros: Keeps water cool like none other.

lets you attatch 3 fans.

Cons: very large although this is expected.

poor planning for ventilation. ventilation is needed for the fans to work so lying it flat is an option but does not work well at all.

Other Thoughts: i placed this over my AC vent (second story so vent is in floor) and it fits over it perfectly. Brings my temps as low as 21c idle and no higher than 39c when at 100% use for hours. i have a phenom II 940 overclocked to 3.4Ghz and planning to push it farther

Pros: This radiator does seem to have good efficiency. With no fans, my 9600GT idles around 105F.

Cons: As others have mentioned, the fan holes are not correct. Going down the sides the holes are about 108mm apart, but going across to the other side the holes are 111mm apart. I had a little trouble getting the forth screw in on my 120mm fan. But I could only get two screws in for the rad grills I bought. http://www.newegg.com/Product/Product.aspx?Item=N82E16811998059 while it's not all that important to get all the screws in, it does give a peace of mind once all 4 are in.

There wasn't an easy way to mount the radiator to my case. my case is a little taller than the radiator and as long, but there was no way I could cut a hole in the top or side to put the radiator in. my case doesn't help as it only has 80mm fan mounts. I bought a 120mm to 80mm fan adapter.

Other Thoughts: I did manage to squeeze the sides enough for everything to have 4 screws, though it did take quite a lot of force. It wasn't easy. This was also with using a drill on the fan adapter holes. However, even though I managed to get the 120mm side on the adapter attached to the radiator, it then forced the 80mm side to become skewed, which forced me to use the drill again so that I could get all the screws in.

$50 and swiftech cant get the distance between the fan holes right.

Rad grills are a must with this radiator, the copper fins bend with the slightest touch. I hope I never have to remove the radiator from the case
