I finally pelted my Bird.

I can’t say that I have the experience that the highly esteemed Dr. Surlyjoe has, but increasing the flow rate helped in my system. Dialing up the speed of the two 120mm fans on the Cooling Cube also helps when the system is under a high thermal load.

Rusty, I would think two radiators would work better if they were side by side instead of stacked.

just a little thought: from what i read you shuldent be using a copper block ans an alumnim resavower. thay will eat etchother away.

yeah sure side by side is better but as you can see in my Tower i dont have enough space for that that s why i ll put them stacked
another question for you Collin the -7Ctemp did you read it in your mobo or you have an external sensor like Senfu or something

 

[Colin]

The temps were measured with the motherboard sensor in the center of the CPU socket. I bent it up a bit to insure contact with the ceramic plate that holds the CPU die. Also, with the center, outside and back of the socket insulated with neoprene, there should be less chance for the temp sensor to be fooled by airflow around the socket.

Colin- I'm not sure if getting a bigger pump will actually help rusty. After all the link that you showed stated:

"Wow, since I was kinda leaning toward the high flow rate camp, I was surprised to find that the best cooling was achieved in the range of 0.5 to 0.6 gpm. "

Now converting that into gph... thats between 30 and 36 gph.

Rusty - I'm guessing that you are using the Aquastealth 2... if so, then from what Joe said on a review of that unit "The pump is a RIO 180; I measured the flow rate at about 38 gallons/hour." which is slightly more but definately around best cooling range. So, my guess is to definately go with another radiator for a peltier system.

While it is true that anytime you have two dis-similar metals imersed in a liquid one will act as an anode and one will act as a cathode. And you will get pitting and corrosion in the anode (aluminium in this case). If you are worried about this then all you need to do is put a small chunk of zink in the storage tank. It will act as an anode to both the copper and aluminium. If you work anywhere that has large industrial equipment they all have anodes in thier heat exchangers and you can probibly get an old one for free. If not, any auto parts store should have them for car radiators.

so i just tried my kit with an additional radiator and fan but it just didn t change anything so the only answer now is maybe my peltier is not working correctly i have a 122W and a 156W )and i didn t see any temp difference that s really weird)or i need a bigger watertank and a more powerfull pump

 

[Colin]

Rusty, what voltage was the 122 watt rated at?

BTW, I have a 172 watt pelt and a 24 volt power supply on the way.

the pelt 122W was on 12 V i finally tried a double radiator but it didn t change anything i may try a bigger watertank with a powerfull pump at least 200gph

 

[Colin]

A larger tank will only delay the time it takes your coolant to reach equilibrium.

 

[rusty]

with my peltier 156W 12v this is what i got but the probleme is that i m on 30C idle so i really don t know what to do to fix this tmp probleme

If you are running at 1596 mHz, that's a major part of the problem. At 12 volts, your pelt is only running at about 110 watts. There is no way it can deal with a 1.6 gig Bird. Nice overclock though!

yeah sure but if i can have -2C idle as u are i m sure i ll have at least 100mhz more

i got another bad news about the RIO pump it s not powerfull enough to run a big radiator with a small one that s really annoying the water stopped when i run it with 1 big radiator and a smal 1 (
