CM Stacker cooling issues.

Just installed the floppy rails, graciously supplied by coolermaster. Wow, am I seriously pissed. I work in a sheet metal shop, and should probly go into the business of supplying this item. Slightly better than generic adaptor rails, but not by much. Faceplate only installs by removing retainer plate. Kinda hanging there, helpless. After beating on it for half an hour, realised there was a compatibility issue. Looks OK, but not very functional. Tried installing a fan on side, but of course whomever installed the grill, stripped out all 6 screws. Gotta lower the torque on those AirWrenches. No chance of using current box, with side fan. Gonna hafta design a replacement side. Looks like side was meant to accomodate an 80 mm fan, not a 120 like the rest of the case :twisted: . Why in God's name would there be even 1 80mm fan in a case touted as be a possibble server solution. Gotta mod the crap out of this thing to get adequate exhaust. Still no HLED display, why in the name that is all that is good, did I not spend a couple of extra dollars, and get the Lian Liu case?

Really, really pissed at this case for so many reasons. Just put a respectable exhaust fan in. Why could'nt Coolermaster do this? Wimpy 120 mm fans are fine for joe sixpack, but joe sixpack doesn't buy this case. I'll gladly spend a few hundred extra dollars in the future, for decent cases. Enjoy you're experiences with Coolermaster cases, but I think I'll go for quality from now on. Later.

It is interesting, but the only problem I had with my case was with the 1 MB mount. As far as cooling, this thing is much cooler than my old LiteOn FS020, which had 3 120's in it. Currently, I have 2 120mm TT Case Fan 2's running at low speed, 1 Cross Flow, also running at low, the original 80mm exhaust fan and an 80mm TT Case Fan 2 running on my Hyper 6 at about 3300 RPMs.

My temps in BIOS are around 104°F for my Athlon 64 3500+. ASUS Probe was giving me wildly lower numbers, so I chunked that, and there doesn't appear to be an MBM5 file for the A8V. Case temps are usually around 86°F according to the AG2 (only 8° over ambient).

I provided a quick how to with pictures on using the floppy drive brackets in an attractive fashion in this forum.

One other thing I noticed, is that the hex bolts on the side are Metric (2.5 mm I think) and are easily stripped using an SAE tool.

As for overall quaility, I have seen some pretty mediocre cases in my day, but this one is built solid. There are things that could have been done better, or maybe just differently. The rear fan mount is very snug and doesn't allow much room for the tape that surrounds lighted fans. The front covers need an easier way to remove them, and I think it is as simple as providing a tool like a modified putty knife to slip in the sides of the covers.

I'll apologize for my rant, but I was severely disappointed with fight I had getting faceplate on floppy drive.

Drilled out the stripped screw, ever so carefully. Cut away mounting (bracket) in side, manufactured 18GA replacements, and Tigged 120mm mounting bracket into place. Sunon's draw alot of air, but CPU is much cooler now. Replacing rear fan with a 3100RPM Sunon, had a nasty side effect without side mods and fan. Alone, the rear fan replacement drew more air across the Raptors, and actually heated the case an additional 6-8C. Looking at getting much higher RPM fan for top exhaust. This isn't that bad a case, just :), if you don't have access to fabrication facilities. Coolermaster didn't make me buy this particular case. With enough welding,cutting, and modding it will suit my needs. Hope the folks at CoolerMaster consider using substantially more powerful fans in future releases of this type.

I have to agree to an extent although I bought my coolermaster knowing that the cooling was going to have to be modded. The stock cooling works fine for someone just throwing a system together and leaving it at that but for somebody, such as myself, that pushes everything in the system beyond it's limits - the supplied cooling leaves so very much to be desired.

In reference to the wavemaster, 1 80mm exhaust fan is not going to cut it, especially one with a low cfm rating such as the one supplied. Also, in order to exhaust more air you need to remove your top usb/firewire/audio panel, this may not bother some, but it bothered me since I have few USB ports in my motherboard as it is. Would these problems stop me from buying coolermaster again? Never, their products are always of the highest quality and I know that they are built to last. I just believe that the cooling solutions offered in some (not all) of their new case lines should be re-evaluated.

Just have to add----on the stacker that the 300mm cross flow pumps cool air all through the case. The 120mm fan speeds seem appropriate for the positioning as does the blow hole. Put some temp sensors in and see for your self. A side blow hole fan does wonders for ram and CPU temps (even the 80mm).

I Put a temp adjustable speed 120mm fan on the drive cage just to check it out, but appears the drive cage front is not designed for a higher speed fan and high speeds seem to create turbulance. The drives stay cool enough with the original 120mm.

Personally have found the air flow to be perfect with all the designed fans in operation.

Yeah I have never got to see a stacker first hand until yesterday and the options for cooling are actually very very good if you use everything available to you. I may just have to buy one :P
