172w tec on maze 4-1

[blowsion]

hi i recently upgraded the 80w pelt of my maze 4-1 to a 172w pelt
i am using an 1500 l/h pump a 360 mm rad with 3 120mm fans and a meanwell 24v power supply

with the 80w tec i was getting idle temps of 28 degrees celcius
with the danger den 172 w tec @18v i am getting idle temps of 30 degrees

now i am getting confused?? what am i doing wrong???

the water in the loop isnt even getting warm

and @ 24v the temps rise by 4-5 degrees

oh yeah almost forgot the vid card is a 9800 pro r360

can someone give me some tips of what am doing wrong or are thes temps normal??

[blowsion]

could i be that they sell 120w tec's as 172w ones over at dangerden?

heres a link

7.9 amps 120watts??

It could be that the waterblock isn't able to draw enough heat from the tec, causing the tec to be less efficient thus drawing less amps. I've heard of this happening before with the Maze4-1. Turn down the volts going to the TEC and you MIGHT see temps go down.

Or get the swiftech block.

well he is already running @ 18volts

i think i got a 120w tec instead of a 172w

is there a way to check the wattage of your tec?

Load temps are needed to evaluate anything, anyone making recommendations about your equipment from idle temps is leading you in the wrong direction.

load 36 degrees celcius

Sounds like bad mounting somewhere.

Either TEC mount onto the waterblock or coldplate.

Or The coldplate onto the GPU itself.

Is there any way you can get a probe onto the cold plate? (to save stripping the entire thing without needing too).

Also can you measure the temp of the waterblock (as close to the TEC as possible)

And get an accurate water temp.

Also double check the voltage your giving the TEC with a multimeter as close to the TEC as possible.

load 36 degrees celcius

What were load temps previously? Load temps at18v?

[blowsion]

36 degees is @ 18v when giving the pelt 24v the temp goed above 40 degrees

I agree there is a possibility of bad mounting somewhere, but your temps with the 80W pelt weren't very good either. It sounds to me like something in your loop is either restricted or just not cutting it for cooling. (Hard to believe with a 3x120 rad) With just a single core rad and the maze-4 80W on 9800 Pro I had - idle temps with low 20's loads and with 172W pelt, idles were in the - teens and sub 10C loads. I did get into the upper teens with max clocks/volts though. Are you sure your pump is pushing the volume it should? Kinks in the line, crap in the rad, something?

FWIW, both pelts I tried ran off a 14V supply. Running a 172W at those volts isn't going to put you near 172W, but the heat load will be reduced greatly. It works out so you are only getting a slightly better delta than the 80W, but with much less heat load from the pelt itself, so better overall temps. Try using lower volts if you have a supply that can do it. I think 14V - 15V is about the sweet spot for a 172W pelt and temp delta vs heat load.
