Blizzard 1230 IV 50MHz with Fan?

Chris1965 · 31 December 2006, 04:01

I have just got myself a nice Blizzard 1230 IV 50MHz for my A1200. As it gets quite hot would it be worth setting up some type of cooling ensure it's longevity?

alewis · 31 December 2006, 15:22

Most definately YES!

keropi · 31 December 2006, 17:58

yep, a fan or some heatsinks on hot ic's can only do good...

fc.studio · 31 December 2006, 20:08

I own Blizzard 1230 IV with 16 Mb no FPU. Intensive use for years and no problems with no fan.
Surely funs can only do good...

blade002 · 31 December 2006, 20:27

Yeah i ran the same accelerator for 5 years with no fan and no problems. Dont Stress.

@chris1965

as blade002 says there no real need to be worried about not having any passive or active cooling (in cramped enclosures perhaps)..

passive cooling
this being said though. cooler components last longer as its heat that eventualy kills components. a small passive heat sink should surfice in a open non-cramped environment or if you wish a small active solution involving a fan.

active cooling
be carfull on installing the fan however as these create emf noise and can cause issues with memory and cpu's if not shielded properly.

I have an apollo 030@40 board (with fpu) and I have added a passive solution to it just to increase its life expectancy... with an 030 @ 50 I would recomend it... especially if its in a regular stock a1200 case.

Chris1965 · 01 January 2007, 03:59

I appreciate all the helpful comments. I didn't consider a passive cooling option. Perhaps that would be the best option.

fc.studio · 01 January 2007, 10:59

You could pierce the bottom removable plastic protection to get some little holes.
This could help to keep no so hot inside the A1200.
However, in the instruction manual I had, I don't remember any advice to avoid this problem.

SilentBob · 16 January 2007, 02:40

My 1230-IV is almost 11 years old, and still lives without any cooling whatsoever, the 1200 is still in its original housing. But there's nothing wrong with taking precautions, of course.

alewis · 16 January 2007, 15:26

I should have quantified my answer :-)

Although kti can last for years, it does die eventually. Parts for our machines are about as rare as rocking horse sh1t, and getting rarer (I'm still after a Phantom DOS for my C64, no chance). Anything that prplongs the life/reduces the chance of failure is a good thing.

What you could try: sourcing an old 80486 heatsink. The chip size is different to that of an 030, so you'd need some way of attaching it. However, the same applies to a fan (which will also need power...). However, heat compund is a sticky substance, and the very very thin layer that is applied may be enough to hold in place, if you A1200 is not moved (nor tower mounted)

A the height of summer last year I had some heat issues with my 1230IV. When the A1200 had been on for 11 hours on a really hot day and I was hammering the CPU and fast ram with Fblit. Machine would hang up on certain operations and eventually crash... so I turned it over and the 68030 was so hot it burnt my finger. That can't be good, so I fitted a couple of fans in the case, not a trivial excercise though. Seemed to really help the CPU tempreture.

Never had an issue before that though, and I used the machine a lot back at Uni in the mid 90's.

Mick_AKA · 18 January 2007, 00:59

In my experience the 68030 on the MkIV and indeed most processors get that hot, every regularly used A1200 I've seen with a B1230MkIV in it has beutiful scorch patterns on the inside of the trapdoor.
Personally I would get some higher feet for the case to raise it a little more, cut a square hole in the trapdoor and attach a nice slim heatsink to it (the ones from higher end 486 and low end pentium chips are ideal)
I think enough power is drawn out of most peoples 1200s without putting horrible noisy fans in them.

Summer in Australia is quite hot too, I have had to add a heat sink and a small attached fan to prevent random crashes. The fan is 12V but I currently have it wired to a 4.5V tansformer that runs the fan slow enough to be nice and silent. This has worked very well but I am wondering if I can power the fan directly from the motherboard? My A1200 is in a standard case but I have cut a hole in the trapdoor for the fan and attached small legs as suggested.

The floppy disk power header might be just what you want, it is normally not supplying much to the drive so there should be plenty spare, and you might even put in a switch for "turbo" on hot days...

That sounds like a good idea, thanks Meega. Does anyone know where I can find a schematic of the A1200 motherboard to help me find the floppy power header and what voltage it would be?

rare_j · 09 March 2009, 22:18

Well I used a floppy to IDE molex converter, then a molex to several 3 pin fan adapters, then a couple of 5v resistors, then the fans. (little quiet ones)

There's probably a tidier way to do it...

meega · 09 March 2009, 22:21

Open up the machine (you're going to have to anyway) and have a look at the floppy disk's connections... it only has two, one is a ribbon cable and the other (with four wires) is the power header. Both black wires are grounds, the other two I think are red for 12V and brown for 5V - use a multimeter to check.

Maybe this helps as a suggestion.

I used a pair of "pc chipset coolers", available at most computer stores.

NovaCoder · 10 March 2009, 03:36

Yep I think fans are overkill for an 030 although heatsinks are a good idea. Also if you're using it in a desktop case, don't install the trapdoor (better airflow without).
