How to improve cooling on SuperMicro SC-750/760ATX Full Tower Case?

[Almighty1]

Hello all:

I was wondering how many people actually have the Supermicro SC-750/760 ATX Full Tower case? I have 3 ADDA 50cfm 80mm fans for intakes on the front, with a High speed 92mm ADDA fan on the side blowing at the CPU HSF and then the high speed 60mm ADDA fan behind the CPU on the rear of the case as well as a high speed 92mm ADDA exhaust fan and it's not making the CPU any cooler than the case's original fans. I even replaced Arctic Silver I with AS3 yesterday and the same problem still remains. My IDE cables are round but I have the SB Audigy Platinum which has a ribbon cable for the media bay thingy and then ribbon cables for the 50 pin narrow SCSI and Floppy. I'm looking for a round cable for the floppy but the problem is they only have it with the 3.5" Floppy connector, not the one for the 5.25" drive as I have both a 3.5" and 5.25" Floppy drive in the machine and I don't know if there is some kinda adapter to connect the 3.5" floppy cable to the 5.25" floppy. Any tips would greatly be appreciated. Thanks.

I beleive That case is made by Addtronics for Supermicro, I beleive it is a older version of the 7890.
Here is a place that has a lot of modified Addtronics cases that you could look at to get some ideas. Jim at coolcases has some great ideas so check his mods out, I love my case he did for me which is the Modified(Hotrod verson) of the 7896 with a few little added extra things he suggested.

Can't help on the floppy thing,sorry.

I have the 750A Full Tower. I've got 2 NMB Quiet Fans in the front, 1 Panaflo In Front, the Stock Sunon 92mm Rear Fan up on top, and a Panaflo 120mm in the back next to my heatsink. I had rounded ata133 cables but I switched to SATA and i made my UDMA33 cables into rounded by cutting and wrapping them in Electrical tape. I bound up all unused wires with Zipties and wrapped my PSU wires in Spiral wrap. No problems with heat and its pretty quiet.

You're right the SuperMicro SC760 is a Addtronics 7890. The link you have is a 7896 though which is supposedly a better case than the 7890 was. So you have to ship the entire case to him. I'm wondering on cases, are the new Thermaltake/Enermax/Antec full tower cases better in cooling than the Addtronics and on my machine, I have two of the HD cages so it can hold up to 12 drives but I wonder if those cases would have the same amount of expandability. Thanks for the help!

Hmm, I thought from your rig, you had a SC760A-300 tower. So basically you have 3 fans in the front? How did you get the 120mm fan in there though? and what happened to the fan that's like hanging on the left side of the case when you take off the left panel? I haven't rounded cables before so I worry that I might accidentally cut one of the wires. Are you using any of the fanholders for the fans though?

to improve cooling...

the case is very deep, so, to properly cool the mobo, i cut holes in the panel, and has 2 120mm fans blowing the entire mobo. i modded the front of the frame for 2 120mm fans.

with most cases, the problem is air circulation and not enough fresh air going to the proper areas.

Good idea but where did you put your fans though? I was thinking about adding some fans too but don't have experience cutting holes. My case temp is around 26C degrees and the Pentium III 1Ghz 133FSB with the heatspreader is 40C degrees or so... Is that normal or high?

One other question though guys, I noticed that the front panel on this case seems to not have good air intake because there isn't much air input due to all the plastic, has anyone actually modified this part and what about the 60mm exhaust fan? Are you guys actually using a bigger than 60mm fan there?

Hey HiTek21,

I was looking at the SuperMicro page on the SC760 cases and it seems for the rear fan, the one I have has the 60mm fan mount. While the newer P4 version has the 120mm fan mount. What did you need to do on yours to get the 120mm fan next to your heatsink to work? And are you using the fan that is supposed to be a CPU Fan backup since I don't know if that actually helps at all. Thanks.
