Cooler Master CM690-II Advanced Case

Cooler Master is a brand name that constantly strives to offer the enthusiast community fresh new products with a proven track record. Although the original CM-690 was launched back in August 2007, that chassis still remains a popular choice for do-it-yourself computer system builders even today. Skip to 2010, and Cooler Master launches the CM690-II Advanced mid-tower case to compliment the CM-series enthusiast product line. The new RC-692-KKN2 model improves upon the original design with an updated look, and adds a new list of features fitting of the modern technology landscape. In this article, Benchmark Reviews inspects the Cooler Master CM690-II Advanced Edition performance enclosure and determines just how much has really changed in this sequel.

Benchmark Reviews may be a website dedicated towards the testing of performance-level products like motherboards and processors, but our Featured Reviews: Cases section proves that we also really enjoy building systems into the finest enclosures available; one of which was the Cooler Master CM 690 NVIDIA Edition Case. The comparison between the originator and successor shouldn't take much memory of the product line, because ironically the Cooler Master CM690-II Advanced arrived to our lab in the same week Benchmark Reviews was building a high-end performance computer system with the original CM690 case.

Cooler Master offers two versions of the new CM690-II computer case, and each version has a standard and windowed model. The RC-692-KKN3 model designates the CM 690 II Regular, and the RC-692-KWN3 adds a windowed side-panel. The top-of-line RC-692-KKN2 model designates the CM 690 II Advanced, and the windowed version is coded with RC-692-KWN2. For this article, Benchmark Reviews has received the Cooler Master CM690-II Advanced RC-692-KKN2 for testing.


Cooler Master's CM690-II is the apogee of mid-tower chassis development. Its development began with the original CM-690 and will be fulfilled with the launch of the CM690-II. This mid-tower chassis improves upon the CM-690 in technical, aesthetic and user friendly aspects. Cooler Master's CM series are enthusiast-grade products that are built for simplicity in design and elegance in outlook. Essential development was begun as a global effort, synthesizing the needs of our customers worldwide. While mechanical innovations were developed by our engineers, end-user suggestions for improving the original CM-690 were added on top of feedback from global focus groups.

Creating a follow-up to the widely respected CM-690 was no easy task. Since the CM690's introduction in 2007, the CM-690 became one of Cooler Master's best selling chassis. Sales records were set, building our brand image as innovators in the mid-tower chassis category. Only now after two years the CM-690 still remains a benchmark in the mid tower category, but experiences new competition from imitators offering near identical specifications with surprisingly similar exterior design. To continually lead the market, Cooler Master built the CM690-II (RC-692-KKN2). The CM690-II defines a new category of functional, mainstream chassis that have enthusiast features.We present a fresh chassis that improves upon the original CM-690 in every way. We believe that with these improvements the CM690-II does not lose any of the original design spirit.

i bought this case and was disappointed with the wc options. you cannot use a 240 rad top or bottom at all. there just is not enough room. the 80mm side fan behind the cpu socket requires a 15mm depth - good luck finding one. the paint job is weak and comes off with the smallest scratch. The included fans are junk and don't push any air at all. quite a cheap feel to the whole case. Nevertheless, good features for the rest but it's just not tall or long enough. I'm a coolermaster fan and love my haf 932 and will definitely look at new Hafx as well

Raysheri, I can only assume you are a troll. It is clearly stated that this case will take a 220 radiator not a 240. If you were buying a case with the intention of fitting a 240 radiator you would check the specs before purchase if you knew anything about building a PC. The paint job is excellent. The fans do the job required of them but there are lots of spaces for more fans if you need them. Finally, the case does not have a cheap feel to it. You have obviously not bought this case, in fact from your comment I can only assume you have never even seen this case in the flesh. Just another pointless troll out to cause people problems in their case choice. Very immature. Now go away.

According to raysheri: "you can't install fans above the chassis as the top will then not fit on, and if you have them pushing through a top mounted rad, the fans would almost be above the cpu and you'd have to remove them and the rad to swap out a processor."

Your remark presumes that a fan cannot be separated from the radiator, and have one part on top and the other below. It also presume that every motherboard positions the CPU in the same location, which they don't. The next time you insult someone, do your homework so you don't end up looking the fool in a public forum.

# Excellent caseAlan 2011-04-26 08:22
I have to support the other guys here. The case is excellent. Setting up my SandyBridge computer inside this was a breeze. Very convenient portals to hide away those messy cables that origin from everywhere. The fans do their job properly, and I have added just one (in the bottom) apart from those initially mounted. I have mounted the PSU upside down so it draws air from the bottom and pushes it out at the back. The fans are not noisy either. I got plenty of room to fit my 570 GTX videocard. The top mounted area with different connections is just superior, wish everybody could design their cases like that. But who wants an other case than this? - not me!

# VERY nice caseDale 2011-06-02 10:45
I had a 4 yr old Thermaltake case that I thought was the cat's meow, but having just received and built with this case, I can see that things have really changed. Wow,quality and features throughout. I must say I am impressed. My very first Coolermaster case, but it definitely won't be my last.....trying to convince a friend to let me build him a system just so I can order another one! This case will not disappoint you....and great value.

i've had one of these for almost 2 years and i love it. my initial build in it was fast and simple. all cables well hidden and tied up. everything neat and tidy with lots of space. then i dropped a h50 cooler on my cpu. rad and fan all in the case off the back 120mm port. still no problems.
some time this week i will be slapping a pair of bfg 8800gtx with dual top/bottom 240mm rads bay res, big bad d5 pump and all that hose to cool these monsters. i've seen the dual rads done with not much effort, and zero case modding. best case i've ever owned. i'll be getting a second one when i finally upgrade to the new sandy bridge's.

# Great review.Imprezzakc 2012-06-07 16:49
Thank you for the excellent review and inspiring Final Thoughts. I have my current build in an Antec 1200 and am considering a new case to accommodate my change over to water cooling. After reading your conclusion I have decided a Cooler Master HAF 912 mid tower would fit the bill. Thanks for helping save some money space.
