Here is a quick picture guide, of what i have done to make water cooling in my AmigaOne. Most of the parts is old used or scrapped parts from my workplace, which i have fixed, so they work without any problems. so up until now this project have cost me nothing.
Sorry for any spelling errors in the text, or bad wording. But i’m danish and english is not my native tungue.
Feel free to post your thoughts to me on firstname.lastname@example.org
Click on any of the pictures to get them in Hires 1632×1232, all pictures have been shot with a rather old 2mpixel Kodax CX4230, so don’t complain to me about the picture quality. :-)
For overclocking, read the part a the bottom.
A quick picture of the old cooler i used to have on the A1, it’s a graphics card cooler from a Gigabyte 9800pro board, which i fittet on the A1. and it seemed to be enough, until i tried overclocking the A1 :-D
Here is the VGA water block from Thermal Take, i like the look of this, with plastic on copper. makes a nice combo.
The bottom side of the A1’s CPU board. just to show that i took special care, to mount the screws with Rubber washers. so not to damage the CPU board.
Going top side again. once again mounting the screws with Rubber washers. The idea for the small rubber feets on the CPU, i got from another Amigaworld.net user, and thought it would be a nice safety precaution to take. so the rather massive Water block don’t crush the CPU core. I also gave the CPU core a fresh coate of cooling paste.
And in all it’s glory, mounted with the water block on the CPU. it might seem a bit of center, but thats due to the fact, that the bolts i used to hold the screws, was so close to the water block, that the water block was resting on the bolt. and not on the CPU, so i hade to twist it just slightly.
From another angle, Where you can see just how close the bolt is to the water block.
While i was at it, i reversed the screws holding the CPU card, so i don’t have to pull out the entire mainboard just to tamper with the CPU card. ( who’s bright idea was that btw.)
From the top side, where the reversed screws now point upwards. the little white strip of tape, is to protect the underlying components from the screws on the CPU card, so they wont be damaged.
The CPU card with the water block, mounted on the mainboard. also i did a couple of special screw-bolts to screw onto the reversed screws holding the CPU card. Again ofcourse mounted with washers, so not to damage the CPU card.
From another angle!
Yet Another angle, and test mounted with some tube, to give an impression of how it will work. The springs on the tube, is so the tube will not bend to much, an then block the water flow.
The Radiator i’m going to use. it’s also from Thermal Take. and in my experience, do a pretty good job of cooling the water on even hotter and bigger x86 CPU’s.
Radiator mounted with a good big 120mm Fan with RPM control. the RPM (Rotations Per Minute) can be controlled either with a turn-knop resistance, or by a thermal probe.
I decided to mount the radiator in the bottom front of the Case, so it will drag cold air in to the case from the outside. and in the process drag the air trough the radiator.
A rather funny looking thing that Thermal take sells as a water level indicator. I decided to use it as a water tank also :-).
Water tank/water level indicator mounted in the back of the case, where normally you would mount a 80mm fan to pull air out from the case
Another Thermal Take gadget. this time the water pump i will use. It’s a rater tiny 12volt pump which will shift 90liter/hour water. well if it’s enough for Bigger and hotter x86 setups, it should be plenty for this
The pump mounted in the back of the case, and a tube going up to the water tank. we’re almost there.
And all the tubing mounted. water flows from the pump directly to the water block. from the water block to the radiator to be cooled, and then back up to the water tank.
I’m in no way satisfied with the looks of this. i think it’s way to cluttered, and plan to redo the tubing some day. but for now it will work just fine.
As you always should with water cooling, is turn on ONLY the water cooling, and not the Computer. to check for leaks, and to get a good water flow with no air bubbels trough the system. When this is achived, you can test if the Computer still works.
I still have plenty of planed things to do on this. eg. a new water tank, make it all look nice, Get a better Case, and so on.
Note: as it seems, this is not the first water cooled amigaone ever. for a nice Amigaone setup with water cooling, take a looke a This
OVERCLOCKING THE SYSTEM:
Yes.. i did it, despite all the warnings about overclocking. i did it to my amiga one.
I figured that now i have a very effcient cooling system up running. I would give overclocking another try.
With the old cooler i had in the system, it would very fast get to hot. but with this new water cooled setup, things are different.
First i tried it at 1000mhz (i’ve got a 933mhz G4). all went fine, it booted to Workbench, and was able to run Dnetc for 1 hour without any problems what so ever. With the fan running on the radiator, nothing got above ambient temp. and the whole system was running like a charm.
Then i went for the top, and set the dipswitch to 8x133mhz. it posted, and uboot reported a nice 1066mhz. BUT! it loaded the kickstart, went to a black screen and then nothing. no workbench
Clocked the system back down to 1000mhz, and started to think about the vcore, having heard so many stories about wrong vcore setings i went to read alot about the settings on intuitionbase.com. and found that my system was currently set to 1.59v which is actually the wrong setting for a 933mhz cpu. And still it was running 1000mhz, with a to low vcore setting. i was impressed.
I then changed the vcore setting to reflect the right CPU. well almost, i followed the instructions on http://www.intuitionbase.com/static.php?section=notes, and set the vcore one step below the CPU default voltage. eg. i set it to 1.79vcore.
Lo and behold, the system booted at 1066mhz, and went straight on to loading the kickstart, and voila booted the workbench. it’s been running dnetc for about 30min by now, and the system is still barely varm to the touch. so all in all this is a pretty „cool” running system.
ps. i’ve got a load af experience overclocking PC systems, so i’m not totally new to this. but was a little carefull doing it, as replacement parts is Very hard to come by.
Word of advice to anyone. If you don’t feel good about doing this, DONT TRY IT!
