I'm tempted to buy one of those recycled 060's but would like to hear from you what cooling does it need when overclocked? What's the threshold from wich it needs colling ? Is it different with the more recent mask ?
Thx
-
No cooling is required. Even overclocked to 66Mhz extra cooling is not really needed.
-
Thx. Is that true for all masks? Or with what version did you have that experience?
THere are also RC50, RC50A RC60A versions also, confusing...
-
@red
depends on the revision.
The 060s used on the CS-MK1 do have a cooler+fan for a reason you know.
my blizzard 2060 on the other was cool enough to touch without any cooling
-
not really needed but i advice you to use a fan anyway , atleast if your tower aint properly vemtilated...oh and for desktop users... USE A FAN + COOLING RIB NO MATTER WHAT!...
its not as hot as 030 or 040 , its just that u dont want to blow yer 060 ... :)

@ Jose
I stuck a heatsink fan assy on my GVP 2060 accelerator because heat is the enemy.
May not need it, but it sure runs cool.

Honestly I don't know if that applies to all masks. My experience was with a XC68060RC50

@lempkee
Does that mean that you would recommend cooling for any desktop 030 or 040? My blizzard 1230IV gets pretty hot; so I leave the trapdoor off and raise the computer above the desk. Is this enough or should I try and incorporate some form of cooling device?
-
Has anyone ever had any experience with one of those solid state cooling devices such as are for sale by Jameco? Sounds like all you do is connect them to a power source and they get cold, pretty cold too, from the specs in the catalog.
-
Like others have said, it all depends on your
specific chip, ambient temp, ventilation and
other factors...mine will eventually begin to
malfunction if I don't cool it (older mask
revision 60mhz clocked to 66mhz).
Unless you wildly overclock it, you will have
plenty of warning in the form of crashes/lockups
before any damage is done. If it's overclocked
at all though I would seriously consider added
cooling...even if it seems to work well for
extended periods.

The desktop A1200 8-) ;-)

I guess there's nothing like trying it out...
What I don't like about cooling is the noise.

Peltiers go down to freezing temperatures, but the heat doesn't disappear - it goes to the other side of the peltier!
You need a beefy heatsink + fan to dissipate the transferred heat, or else the peltier will break.
So basically this method will cool (freeze :-) the CPU quite well, but in the end it'll be hotter than the bare 060. (depending on revision, of course..)
Both my 060s run just fine without heatsinks, they've only gotten warm a few times, but usually they run cool to the touch.
Edit: I just googled up a little info on peltier elements.. (http://www.heatsink-guide.com/peltier.htm)
Basically these might aid in getting the CPU clocked higher.. I don't know if anyone has ever used this method in Amiga overclocking.
-
abou27: yes i do, though its not needed really but its a shame if it dies (overtime) just because u didnt cool it...
but since you are in a desktop, well...there might be toomany reasons for you to not mount a fan on it, also it wont be as quiet any more;(
but then again i never seen a 030 getting blow due to heat, but 040's i have seen bucket loads of..., and only seen 1 060...

@lempkee
I'm not bothered about noise; but, yeah, space may be a problem! Was considering a couple of fans beneath raised A1200. Thing is, I'm not too sure how hot is too hot! With mine, can hold finger on it, but quite uncomfortable - too hot?
What do you reckon about glueing home-made heatsinks to the chip? Good cheap solution or oops, hope you didn't like your chip!?
Cheers for your feedback once again- hopefully one day I shall be able to help you out with a problem!

@ Abou27,
No, never "glue" anything to cpu. Use heatsink grease, avail. @ any electronic shop.

@Abou27
Find a good "486" fan/heatsink combo, and run the fan at 5 or 7
volts through a cheap wall converter...the fan will be much quieter
then, and should still be plently of cooling for your CPU.

What about this (http://www.radianheatsinks.com/Products/Standard/MiscStandard/MiscStandard_2062.htm)
(http://www.radianheatsinks.com/Products/Standard/MiscStandard/images/2062_200.jpg)
Width (in) Length (in) Height (in)
2.82 2.45 0.2
Ok, I know it's nothing special but it's thin. It would probably fit an A1200 desktop provided a means to get it well fixed, and it would be silent.

My personal experience without overclocking:
030, gets pritty damn hot but doesn't need heatsing nor fan for any Mhz model.
040, gets extremly hot and to ensure a healthy system for a longer time a 25Mhz model need a heatsink and a 40Mhz needs a fan aswell.
060 is a bit hard to say with all the different types but usually none of them need heatsink or fan as long as they ani't overclocked though to ensure a longer life span for these expencive CPU's a heatsing should be applied anyway
When it comes to overclocking there is one rule that always apply... ALWAYS use extra cooling! :-o
030 definitly need a heatsink and probably a fan.
040 shouldn't be overclocked since it already run very hot but I'm sure there are ppl out there doing it anyway and if you got a wathercooling enviorment it would probably come in handy right about now.
060 can be overclocked but how far you want to take it is realy up to you and the type of 060 you have (and what you value the most, more speed or longer lifetime). Although I definitly recomend both heatsink and fan for any overclocking of the 060... 55Mhz for any type of 060 should be fine without extra cooling... 60Mhz definitly need a heatsink for the 50Mhz versions (standard or "A model"). For 66Mhz you need both heatsink and fan if it's a 50Mhz version CPU you got, if it's a 60Mhz version a heatsink should be enough. 75Mhz should realy just be tried wit the 60Mhz version and then with both heatsink and fan but I guess you can do another wathercooling project here for the 50Mhz models also aswell as for the 60Mhz if you want to try puch it alittle further. Now this was all true until I read about a 100Mhz 060 turbo for the Atari... It uses the newest of 060 (that have some new tech) whith no Amiga turbo are equipped with (yet)... If you get hold of such a CPU you should be able to puch it to this extreme aswell but as far as I could see it needed some heavy cooling not to burn. :-D

@Abou27
Well... I was in the same dilemma as you... how do I keep the heatsink in place? Well.. "long" time ago 486's sometime came with a sticker that you put on the CPU and then stuck the heatsink onto... those would be ideal though they are hard to find here where I live... what I did was to put "heatsink grease" on it as sugested and then clean the corners and use just a little compound glue there... it's not ideal but it works (just make sure you get a glue that can withstand heat... I use my solusion on a 040/25 with just a small heatsink (atm till I find a fan) and I can tell you it gets hot... blister hot even!).
-
Well, you can use heat conducting glue or heat conducting adhesive pads, but of course they don't conduct heat as well as thermal grease / silver paste and a spring clipped cooler element.
-
And you need to find those things aswell, most places don't have any. Also in my case the 040 is in a standard A1200 (with extra high feets) and the heatsing sticking out a little underneath and I want it is well and surely stuck to the CPU.
