How hot should the 68030 processor run?
I had it running in my blizzard 1230 for a few hours yesterday and it burnt me when I touched it. :-o
-
They run quite hot, much hotter than the 68060
My '030 on my Blizzard 1230 also runs quite hot, I've drilled some holed in the trapdoor so there's some extra airflow around the card but I can still feel a hot spot underneath the table from the 68030 :lol:
-
I can't even have my trapdoor cover on. The memory stcik sticks out and makes the amiga wobble.
I'll have to make some sort of stand for it so it sits flat.
-
Are you using a huge 64 or 128mb simm module?
-
Yes, it's 128mb.

Overkill :-)
32mb will do fine, IMHO only expanded A1200 needs more than that
-
It came with 128MB.
And cost less than the 32mb version at amigakit ;)
At least I shouldn't run out of memory. :-D
-
Oh, so huge SIMMS add to the production of heat? Didn't know that. I ran my B1230 with only 16MB and it never got hot at all. My 060, on the other hand, get so hot that I can burn myself if I touch it... =)
-
Don't know.
The actual processor gets very hot (+50 degrees c). The heat on the memory stick seems to have come from the processor
The memory stcik probably stops some of the heat from escaping.
-
the heat produced depends on the cpu revision. i dont know where you can get the numbers anymore, but i had a late revision 50mhz 030 that you could put your finger right on. it was hot but it wouldnt burn you.
-
My old 030/50 would heat crash when running Imagine (lots of FPU math). Removing the trapdoor and jacking up the case with four one inch rubber door stops fixed it nicely.

You guys think a 68030 runs hot? You don't know what hot is! I have a laptop with a 3.3V Pentium 166 and no fan. That thing really cooks but it's still stable. And that's nothing compared to the latest x86 CPUs.
-
What are the latest x86 processors like?
The fastest one I have is a 500MHz Pentium III so it only needs a basic fan and heatsink and doesn't really get hot enough to fry the other chips.
(please say if you understand the joke in that last sentence) :lol:
-
I have an AMD 2800+, just slightly overclocked to 2.5 Gh. It has an excellent heat sink/fan setup, but you sure can't touch it - and that's nothing compared to my new graphics card, an ATI 800XL!
Most of the newest intel chips run so hot they fry unless water cooled!
On the other hand, my '030 A1200 run very cool. With 128Mb of RAM, the CPU is only warm to the touch.
The '040 is the hottest Motorola CPU (at any speed) - I couldn't even run an '040 in my desktop A1200. It was way to hot, and a fan would not fit in there.

steve30,
the 68030 not needs any fan,so if runs very hot leave it alone...thats all and that's normal
also the 68060 cpu not needs any fan cause 3.3 volts technology
only the 68040 needs a fan so the use of that 1240 turboboards are not recommended on a normal A1200 case
bye, Laser

I guess not enough space for a heatsink and maybe a fan?
-
Laser: Do you have a bad stutter?
;-)
I feel a little uneasy about being able to feel the heat of my '060 through the SIMM, the air, the trapdoor cover, some more air and half an inch of wood.
Can anyone reccomend some sort of silent heatpipe/cooler for A1200 desktops?
I've seen some copper memory module coolers in a local shop but not for 72-pin SIMMs. It'd be interesting just to get some sort of thermometer device in there just to keep an eye on temperatures - particularly with a PPC/BVision combo.
Anyone transplanted an A1200 into an A500?
:-D

On my Blizzard 1230IV the 68030/50 was too hot to the touch and specially in the summers it use to crash often because of this. All these with the trapdoor cover removed of course. I don't know why ppl keep it on, anyway.
The overheating/stability problem was fixed when i removed a part of the plastic case of my A1200, just to expose the CPU and screwed a fast fan over it.

Oh, sorry about the multiple post but it's not my fault. (It happened to laser too) When i press the submit button i get an error message "the link contains no data" or something instead of the "thank you for your submission"
-
I used to have an Elbox 1230-II, on which the CPU ran extremely hot. I put a heatsink from a PC's southbridge (those are genereally quite small), and that fit fine. The system ran much more stable after that.
-
Those x86 processors sound as if they get too hot. I don't think I'll be upgrading mine in the near futre then if it needs water cooling!
I have not put my A1200 in a 500 case, but I might have a spare 500 case soon so I might put a PC in it.

It's hard to fit any fan on the CPU in the desktop case (may as well say impossible).
There is an interesting article in CPU magazine (pp39 of the March '06 issue) on using thermistors to keep track of just how hot the component is. This way you'll know if it's getting too hot.
PS - any of the RAM heat sinks can be trimmed to fit your RAM.
-
I would attach a small vga cooler, got one here which is about 5mm high with a small fan.
However I think due to the very low power consumption of the 030 you can get away with only a small passive heatsink, if there are some airflow where the cpu sits otherwise it would be next to useless.
Remember cool hardware is happy hardware :-P
Going back to my happy-place ;-)
-
My athlon palomino 2100 is slightly overclocked to 1950Mhz. it used to run at 60C idle and was noisy, now 18C on chilled water. I always fitted fans on all my Amiga accelerators 030->060 but only the `040 ever had any heat-related instability.
-
It seems that you never yet get the plaisur to put a finger on a working Blizard 1230-IV/50 with a 68882 FPU @ 50 Mhz :-D, the 030/50 next to it feel a bit cold ;-)
-
For cooling a 030 I would get a old northbridge cooler. You might have to cut it some to make it fit. Also a laptop style 20mm fan should be enough to move some air.
Regarding newer systems(x86). The latest p4 series require extremely much cooling. The require coolers that can handle 100w+. You don't have to go water cooling though.
The newer AMD systems(a64) however are easier to cool than the old XP series. But good cooling is always needed today.
I remeber reading somewhere(think it was tomshardware) that they tested if a modern cpu(athlon 1200mhz at the time) could handle boot without heatsink. They some laser thingy to measure the temp. 1-2 secs. after pressing the powerbutton the athlon reached 300 degr.(C) and the cpu died(probably long before it reached 300)...
-
OMG!!
I never knew they got to those sorts of temperatures. I only thought it was high end processors thatgot that hot.
Computers are going to end up replacing central heating systems soon. :-o
-
My 030/25 overclocked to 40mhz used to operate around 15 degreed C over ambient, so about 35 on a 20 degree day which is cool. I had fitted a small heatsink to the PLCC, stuck on with thermal glue, without it, the heat output was worrying.
If you wanted, you could scrounge an old heatpipe/heatsink/fan assembly from a laptop, many have very low profile unit that adds about 5mm to chip height.
As for running huge amount of RAM in an Amiga, I noticed access speed drop with larger sticks, I guessed it was because of additional adressing overhead?
-
I wonder if the old FPM uses more juice or creates more heat than the newer slimline EDO...
It's probably best to keep to a single SIMM if you want to keep power consumption/heat down and speed up.
The Blizzard cards throttle to 70ns if two SIMMs are used on the main board and on the SCSI card. Not sure about the PPC cards with integrated SCSI (do they have 2 slots?)
