That's what I'm talking about when I say "I wouldn't send my prommie to anyone else". I really wouldn't.

yep she seemed nice.

well tommorow i will be short handed at work so i wont be in here much,but i am working on a evaperator cover for TheDudes prommie.
i am tried of hand making them from metal.so.......
i have started a fiberglass one i am hand making and then i plan on making a mold so i can pour them out alot easier and quicker.i have in my mind making one cover that i can adapt to amd or p4 without worring about turning the head for anybodys board.
but i will be investing in some hitech ceramic insulation.will cost me close to $80 just to get some to test with and pay shipping to me.
i maynot need the ceramic insulation but i will be playing with it anyways.

one small thing i have the one prommie with the GPU block of bakers running -41c loaded right now.

it seams to doing fine.will drop to -47c unloaded but seams to hold -41c with my load block,not too bad considering it was doing -30c stock loaded.

**bowman1964** · 08-12-2003, 07:01 PM

well been busy latley but have almost finished the GPU prommie,it is just running every night as i watch the pressure and temps so i am sure it will be fine.
seams to be holding a load @-42 to -43c which is pretty good.i think it would be about 3c colder but the upsidedown evap is always going to be slightly warmer from the liquid wanting to run down.

But if it wasnt for this latest designed GPU evap that baker and me worked the bugs out on this wouldnt be very easy to acheive.as the evap is specially desinged to hold the refigerant close to the cold plate giving the coldest GPU temps possable.

here is a pic of the finished unit as i placed some finishing touches to the insulation

**bowman1964** · 08-12-2003, 07:07 PM

here is something i am working on too.
i am tring to make a outer shell to house the CPU evap which plays double duty as a hold down device.
it is a rough shape right now as i hand laided the fiberglass resin and made this shell.
i have to mold in pressure points that contact the CPU evap so i can apply pressure to keep it seated properly.
when finished i will try and make a mold and pour the finished one in one last step.

**bowman1964** · 08-12-2003, 07:38 PM

ok i gotten in WxChaser's mach II and she is nice....

well itwill a little tougher to mod this one because i have to make be a jumper to make her run.she wont fire up without a pc attached(or at least she thinks so LOL)

anyways here are some pics of the internals,i see a few improvements over the mach I's

Bowman I curious what changes you have noticed on the Mach II cooling head ?? I know its got a completely different control unit, just wondering what other changes you see ?

**WxChaser** · 08-13-2003, 03:10 AM

Thanks a lot bro - I feel relieved just seeing a picture of the unit now. Appreciate you posting up the pics.

I wondered with the new Mach II software/firmware setup how it would fire up initially.

By the way awesome job on Hobocrow's unit, we've been talking back and forth. That GPU block should really help his scores immensely, gotta love the load temps.

**bowman1964** · 08-13-2003, 04:36 AM

well first...i think the controller is looking for a signal from the display before it will start up the unit.because i have one connector that i asuume is for the display.and that has to be the problem.

i just plan on somehow getting to the connectors at the back of the compressor and give it current directly.bypassing all the fancy electronics.

the unit has a couple of enhancements over a normal prometia.

for one the head is placed at a 45 degree angle to allow it to turn to fit any board without having to twist very much.

the head itself is redesigned,not sure what improvement it will give,all though it is poured in a mold not machined plastic like the older one(which is cheaper to do,the primary reason for the change i believe)

the hose is more flexable and slightly longer.

the fans are larger and more effecient design.

the return hose is completly rerouted,it is ran over and around the top of the compressor.this is giving more time to allow the extra refigerant time to boil off.so it allows them to slightly over charge the system which will help slightly on the load temps.

other than that i see no differance.actually it looks like the unit cost less to make than the old mach I does.as there is no display they purchaced to run the system.the mach I display runs around $100 alone to purchase .but this may be offset by the lcd display they are using now.

i will keep everyone updated on the progress.

Hi, the MachII has a restart delay of 2 minutes. When you first put the power on, and had a display you could see it counting down 2 minutes.
Maybe that is why you think it don't work without a PC :?
Also, if you take the power off, and then turn the power back on, again there is a 2 minute waiting time.

Just so you know....

Well thanks that may be it.i will check it out tonight.i hope that is it.will save me some work

**WxChaser** · 08-13-2003, 06:08 AM

Thanks Vatt - not having used the Mach II yet I have no clue. Tekwerkz shipped the green LCD display to me along with the CPU kits, case, etc, but bowman got the top case to mod.

**WxChaser** · 08-13-2003, 08:16 AM

Bowman - can you please check the LCD cage holder on the Mach II for me? I want to know if it has the extending bracket sticking out like Scott's in his thread or not...so I can figure out how to mod it to fit. Thanks.

Bud i will post a pic tonight but there is no opening in the front of the case at all.it is completly differant than all the others.the only opening is for the condensor.

**TheDude** · 08-13-2003, 08:35 AM

That makes sense. I thought the mach2 didn't come with the LCD display?

**bowman1964** · 08-13-2003, 08:35 AM

ok look here from my previous post pic.from the inside out over the condensor there is no opening.

**bowman1964** · 08-13-2003, 08:36 AM

dude call me at work

**WxChaser** · 08-13-2003, 09:04 AM

Thanks man - may try to call you at home while I'm at work this evening to see how it's going. Catch you later.

And Dale...I had to buy the green LCD display, it does not come with one (choice of green or orange LCD's).

Is there an opening in the front plastic cover so the optional display will be visible, or is the display only usable with the Lian Li kit?
