Cooling for A1200

[irishmike]

Hello All:

My Miggie is an A1200 with Blizzard 1230 MK IV accelerator card installed.  They have no heat sink or fan on the 68030 processor and I think it gets a bit too hot in there if you use the Miggie for any length of time.

I was wondering if anyone had suggestions on cooling the unit a bit better -- other than obviously towerizing it (which I am still considering pending getting the money together to do so ;-))

Suggestions would be welcome!

If you haven't already, yank the metal RF shield.  Keep it, but just get it off the computer.

A '486 cooling fan/heatsink combo attached to the 030 should keep it icy cold.  If you don't want to monkey with the fan's power connection, at least use a heatsink.  You could also jack up the bottom of the 1200's case a bit by sticking a stack of two coins under each "foot" of the case.

That's my recommendation anyway.

cool.  Is there any particular cooling kit that someone recommends?

I have a GVP 030@40 in my A1200 and have never done anything in the way of added cooling. It's been that way for the last 10 years. The case doesn't feel any warmer than the laptop. I did have it up on little quater inch (5mm) rubber feet for air flow under the case at my last place.

Yes I read B00tDisk's reply.  I am seeking out a 486 fan,heatsink, and glue for the project :-)  I was asking if there was a specific kit made ready for this configuration, or least that is what I meant by the response.  I like to have more than one idea to try :-)

Thanks for the response, and that may well be the best way to go.

Is your '030 really getting that hot? None of the 68030 Amigas I use have ever had any cooling on the CPU, and have been running 10 years plus. They run from 33MHz to 40MHz.
My 68040 machine is another story. That puppy gets HOT and needs a heat sink/fan.
Be craeful you don't run out of room adding a heat sink/fan to an A1200 desktop.

Man, your 030 need somthin like this


 :-D

nevermind, its a JOKE  :crazy:

EDIT: just found proper heatsink for 040

If you use the trapdoor cover with the CPU card you can start by replacing it with something that gives more airflow (I used the metal mech of some speakers for my A1200, gives both good airflow and still gives protection to the card).

A realy lowprofile 486/P1/videocard heatsink will do (then you might come away with not having to add extra height to the case).

On the other hand... I've had a Blizzard1230 running almost 24/7 with trapdoor on and no extra cooling without issues for years, so might just be a comfort of the mind thing.

This is how I did it: Two fans connected in series, one blowing in and the other one out.

060, delfina and scandoubler etc

@Chain

that awsome!!!!!!!

but i think youll have trouble getting the lid of the 1200 back on after installing it. :lol:

:::warm the lid with a hair dryer and then stretch a bulge on it :-D

[irishmike]

I suppose I could simply fix a fan or two to the outside top as well.  Both pulling.  :-)

What is the card in the middle of your pic that looks like it has 2 RCA jacks coming out of it?

That is the Delfina Flipper sound card.
