Amiga Hardware Issues and discussion / Re: CD32 internal fan?

@F0LLETT

When I said throttle I meant a system wide throttling that Proxima III puts an Amiga through. It's not really the CPU that gets pushed in that game it's the custom chips.The CD32 grill is tiny co.paredto an A1200 and with a spinning drive an 030 sysyem can get hot enough to cause the HD to shutdown!

@FOLLETT

Why what? This isn’t SX32, this is SX32 Pro, 50MHz 68030 (and optionally 68882), I got one too and it does get warm, especially with spinning disk installed.

Oh, nice. So the passive heatsink and this grill will suffice if CPU boost comes ;)

Thank you

I had a standard sealed box, everyone gets. Just the heatsink and it runs just fine for hours on end.
I used to leave it running for over 6 hours overclocked running some intensive games / demos.

I have to ask why?

Seems pointless to me. There is no way it would generate enough heat to cause any issues.
I ran my ACA1220 clocked at 50MHz for 8 years, 8 hours a day. I also had stock trapdoor cover.
It was never unstable or crashed once. Unless its running at 60 -70 degs, I don't see point.

SX32, would also not throttle CPU. Its set to one speed and runs at that speed all the time.
So the heat generated will not change that much. Where as the ACA1220 could throttle cpu using a governor.
I never saw any point and just ran it as full speed all the time.

I know this is an old thread but I wanted to be on record as saying it is possible to mount a 40x40x10mm fan inside the CD32/SX32. It was positioned between the hard drive (spinning) and memory simm. It is very tight so is held in place by friction and sits on top of an FPGA of some sort so it's in line with the grill! A fan guard with sections of the sides cut out was glued to the bottom of the fan to promote air flow sideways from the CPU/FPU and then blown out of the top grill!  Power came from a molex adapter from a spare CD32 psu I had. It keeps it stable unless it is throttled for an extended period of time playing something like Reshoot Proxima III!

I would recommend a IDE2CF card solution to reduce the heat further.

The fan was this model: Noctua NF-A4x10 FLX

Possible. However fan is not needed, it never goes over 50 deg even when overclock set on all the time.

Already being discussed. My GS was the test for overclocking.

Is it possible to plug in a 5V small 2pin (20x20mm) or a small blower fan somewhere on a board inside the A600GS? I have couple of them and I've made a custom rear grill for testing so the hot air can go out. Thanx
