Guide to changing the MCW50-T pelt to a 172w

[KnightElite]

No, no VGA blocks come made to fit a 50mm TEC. You could probably mod something though.

Well looking at the pic - http://www.dangerden.com/images/maze...gpu2_large.jpg and seeing the screw holes that go through it, I don't think its possible.

It would likely deal with drilling new custom holes and stuff....which would be too close to the existing ones because 50x50 would only be an extra 1/2cm sticking out each side.

Why doesn't anyone make a 50x50 GPU block??

I absolutly hate the fact that the hot plate touches the water cos it makes my water basically boiling temp - 40+ degrees celcius after 20 mins of use...bugger that

I was told by my mate running a DD block in a closed loop that his water doesnt even move temps from start to finish....prob gonna try that

[KnightElite]

Ummm... Creative. If the water is getting hot, then it is working. Obviously, the heat has to go somewhere, so the problem is more likely to be with your cooling than with the design of the MCW50-T.

[sandman]

Yea, it's still the same amount of heat to be dissipated, whether or not it goes through copper first doesn't matter.

The only reason I dislike it is because it can only be a TEC block then.

[Soulburner]

So which is better? Obviously it sounds like a good idea to disappate all that heat off the TEC, but how much does it actually help vs using the MAZE4-1?

You are no where near boiling temp, you have about +60c to go before it would start to boil.

I just orded a mcw50-t and a 40x40x3.2mm 172W peltier I allready have a 200W meanwell that can give me the 24V so I let you guys know if it worked out well with me to.

I get what you mean though, 40c is 100 degrees F, thats freaking hot. At least that tells you your setup is doing its job of removing it all from the TEC. If the water wasn't hot coming out of the block I would worry.

As long as its cooled down enough when it comes out of the radiator.

I have done some checking and the water seems to be the same temps all the way around the loop which to me isnt a good sign.

Im awaiting a block from Silverprop and will try that in the new year. Not going to do anything except play games for the rest of the year :thumbsup:

[Soulburner]

The Silverprop is TEC compatible?

I did some reading of a half dozen reviews on the MCW50-T and even with the stock TEC (12v on your PSU makes it do 53w) they all were getting temps of 10c full load on an overclocked 9700 @ 400-420 core. With this 172w at 12v, which should be around 85w, I should be seeting below zero at idle...I don't really see how much you could improve over that . Especially since the other blocks (DD MAZE4-1 for example) don't cool the TEC as much. That's probably why the Swiftech gets such good temps with only the 53w heat removal it has. So I decided to go with it over the DD (I couldn't find any reviews on the TEC model).

The current Silverprop one isnt, but Jeremy is machining a TEC version of the block. Its been delayed now a few times which is a bummer, but should have it in the new year :thumbsup:

I have a spare 350wat PSU here, could I plug the MCW50-T to that and get more watts thru the pelt? Maybe that could get more me mhz on the card etc?

I must admit I havnt checked the temps with the 9800 cards but iirc I was getting about ~20dc idle and about 30dc load with the MCW50-T on a 9700 Pro and room temps water being heated up by pelt

PRob do some investigating and find a new optimum setup for the water

[Soulburner]

Woah your temps increased by 50c? Sounds like your card is overloading the TEC! I hope I will have better success with a little more power at 85w...should be enough to keep that thing cold under load I think.

And you can only get more watts from the pelt with more volts from the PSU.

EDIT read that wrong, thats approx 20c, not -20c.

well i just slapped on my mcw50-t with a 172wat tec and got 430core no v-mods and my temps seem fine so i gl with ur setups

What are your temps m8?
I am about to do the same with the same block for soft modded 9500 256-bit np.
430gpu it produces 17C with DMark2003 full test run (stock MCW50-T)

So if I have the mcw-50t modded with a 172watt pelt running @ 18-19v, what kinda radiator will I need to take all the heat away. I plan to have 2 loops (cpu/gpu), and I already have a dual 80mm black ice radiator....but somehow I dont think that will be enough especially since the gpu loop would be 3/8" ID tubing. Would a single 120mm pro-core radiator be enough?

EDIT: woah just noticed how old this thread was

....still one of the "best" 24/7 mods available....

EEEeeerrrcchhh! I can hear the crypt doors opening!

This is probably a stupid question, but how do I regulate the amount of voltage to the pelt?

This is probably a stupid question, but how do I regulate the amount of voltage to the pelt?

By adjusting the output of the powersupply. This would mean that either your power supply needs to be adjustable, or you need to build some type of voltage regulation circuit to adjust the voltage.

EDIT oops posted to wrong thread... too many windows open

[Cupcake]

I got a 40mm pelt that runs 168w @ 15v

I think thats the most efficiant for people that wanna run 12v

im estimating its around 130 something

I had one on my 7950GT and a maze 4
