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!

[irishmike]

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

@K7HTH

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.

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?

@fragment

Cool.  I was just curious :-)

@MrZammler

Perhaps I should raise it a bit for better airflow... the main thing I think I am "smelling" overheating or perhaps there is a lot of dust inside?

@everyone

I am not saying this to offend anyone, but the person who owned my A1200 prior to me was obviously a smoker and there is the fun yellow stuff on the electronics that I have been carefully cleaning off with denatured alchohol on parts I can see, Maybe a good cleaning on the rest would be in order.  The unit produces NOT a "burning electronics" smell, but a "hot smell". (hard to describe) after it has been on for as little as 2 hours.

so the question becomes:  Is my Blizzard 1230 MKIV card at 50 mhz?   I do not know the answer to this.

Is there a way to tell easily without taking the whole machine apart.

Just a little background on me:  I have been a PC and Macintosh Technician for over 18 years.  I know that back in the Macintosh LC days, they did at least have a fan pulling air through the case even on the older non-PPC processor.

IMHO:  It is better to cool a chip that theorhetically does not require being cooled than to be sorry later because it fails... especially at the prices for the accellerators :-)

@doctorq

Yeah, just because I am a technician does not mean I want to open up my box and look at the processor and cross reference the part number and etc ;-)  I imagine that sysinfo would also tell me the processor speed?

The speed according to SYSINFO is indeed 50 Mhz, actually running at 48.40... so cooling seems to be in order IMO.

Ahhh, you assumed I installed the Accelerator card.   I actually bought the A1200 as it sits.
