Waterblock/peltier

[pi3573]

Should I let my Waterblock/pelt achive its lowest temp(-28.6c)before I turn on my pc,at that temp I have lots of ice all over the waterblock/pelt.The system is on its side so no problems with water dripping,just wondering if any damage to the cpu could occur.

Even with the computer on it's side, it would be advised to condensation proof the socket, motherboard and the top of the chip around the CPU die.

I usually let my coldplate get down to the temperature it normally runs at with the computer on before booting. There is no need to let it get any cooler. It's well worth the time and expense to put a temp sensor on your coldplate.

I got you covered Isealed the inside of the socket , around the outside of the socket put closed cell foam inside of the socket used dielectric grease on the socket pins and well...yes Im ready.

er.. i would say no because there would be a huge temp change when you turn your computer possably causing the cpu to crack

how powerful is ur pelt

[Burning Phoenix]

I have a 72 W peltier on my DD waterblock but it doesn't see to be enough. Not the peltiers power itself i'm disappointed in but the small area it uses between the coldlplate and the waterblock. I may be wrong but it seems to me it should use the entire width of the coldplate such as using 2 peltiers. I'm only getting 14-16 C idle and 25-28 C under load. I felt the outer edges of the coldplate and they feel really cold , colder than MBM shows. Doesn't make sense! Any Suggestions?

Burning Phoenix - You need a larger pelt to deal with the heat from a P4. It's normal for the coldplate to be cold at the edges, the CPU's heat is in the center. Depending on the CPU and pelt, it's common to see a 15 C to 20 C difference from the temp at the edge of the coldplate and the CPU temp.

Glad you responded to that question of mine and helped confirm that was the problem. I was also wondering if using (1) 156W TEC ; which would concentrate it's heat absorption at the center of the waterblock ; or using (2) 72 W TEC's ; to evenly pick up heat from all areas of the waterblock ; which would be better?

[Colin]

I don't know the answer. Since you already have one 72 watt pelt, a second would be the logical option. Also there has been some talk about the Maze 2.2 coldplate bowing sightly in the center if overtorqued and set up with only one pelt. I have not verified this personally, only read about it on other forums. Using two pelts would minimumize the posibilty of this happening,

just wondering

has anyone stacked a 156watt on a 172 watt or visa versa?

[Colin]

To stack pelts, the pelt on top needs to be twice the wattage of the pelt pulling the heat from the CPU. I have played with the idea of using three 172 watt pelts and a modified Maze 2.2 to do this but that's a whole bunch of heat to dispose of.
