IIGS cooling (without a System Saver)?

[Byrd]

Hi all,

I'm looking at improving the cooling of my IIGS, I like the Kensington System Saver however it has US-centric plugs and I suspect is not 110-240V switchable (I'm in Australia, different plugs + 240V)  

The IIGS I own was used in a library for years, without cooling, and has a TransWarp GS card + GS-Plus RAM card and SCSI card - with no history of failure.  I recently picked up a CFFA3000 card for it and think I should improve the cooling - any tips here?  It has a fan clipped to the side of the PSU but this merely blows around hot air.

Thanks

JB

A pancake fan blowing out a rear card slot opening?

Close Bunsen...

Kenneson (sic.) used to make a flat System Saver for the IIgs. The IIgs cover has some slots on the top which heat is pushed out by the internal fan. The "System Saver" rested between the IIgs and the Monitor and a fan inside pulled more air out from the slots. In the front there 5 or 6 power switches to turn your devices and had an internal surge protector; one of those switches was a master switch to turn everything on and off at once, the others controlled various outlets in the back of it.

The OP doesn't want and/or can not use a SystemSaver, because they live in Australia, which has different voltages and power connectors.

My IIgs has a small fan attached to the front of the power supply. There's a header on the motherboard to power such a fan and you can probably add stand-offs to the vented front portion of the power supply.

I'm at work and the system is at home, I'll try to get pictures of how mine's set up tonight. I have RAM and a hard disk card in mine, but nothing else, so I don't have the fan plugged in, but it's in there and you can get an idea of how it's set up.

Bunsen's idea of using a little fan set up on an available slot opening might also work.

As promised, my IIgs.

Basically, somebody attached a random fan to the power supply and plugged it into the fan header at the back of the motherboard.



I leave the fan disconnected because with almost nothing in the system, it generates almost no heat.

Also, I remembered (saw) the name of the storage apparatus mine has in it: Focus hard disk card. I've got a 32-gig CF card connected. Unfortunately for all, the GS/OS native file system doesn't (currently, at least) allow partitions over 32 megs and while the FST for HFS partitions allows more than 32 megs, it's unreliable, so I've just got like eight 32 meg partitions on it.

I was thinking more like this "PCI fan" type, uniserver.

The power supply fan was actually sold by Apple as an accessory. It really didn't help with cooling though.

 

[Cory5412]

It must have done something, because the impressions I've heard of it, both the configuration I have (which doesn't specifically look like an official Apple accessory) and the official Apple fan, which I haven't personally seen one of, is that it's sufficient to cool a IIgs that's mostly full of stuff.

Perhaps not "every single slot full of high powered things" but it should be sufficient for a transwarp or a zip and two or three other cards, as far as I can tell. (Though, I'd be interested in whether or not you need the fan at all if you really only have a transwarp and one or two other cards.)

Thanks all for the suggestions, Cory I have the 60mm fan mounted in the same spot but it tends to not be the most effective solution.  The Transwarp GS is the main bringer of heat, but I can free up cards around it - thinking of rigging up a wind tunnel of a fan at the front pushing air exhausting out the back (another fan at the back).

yeah i was originally thinking the PCI card slot fan as bunsen suggested... the only problem is there is no PCI slots.  and no way to mount that... how ever...  there is rectangle shaped holes/ports in the rear case, That I think you could cleanly place the mouth of the blower that i suggested into. that way we are pulling the hot air from inside the case and blowing it outside.
