Much to gain from thicker rads? - Page 3

post #21 of 37
Thread Starter 
I see that. As i said above all the test we have seen regarding water temp difference only shows "Water in" vs "Water out" im testing two places within the loop. If i move the temp sensors to the start and stop i could see less difference. The two places im reading has no rads between them.

As said, the monitoring system is showing correct temps when idle so if something is wrong with it it's something weird couse i see the same difference on all the "temp headers"

Look at all the different heat loads and different fan speeds and notice how little the water temp changes, something isn't right with you monitoring system!

Depends where he has the sensors and how the loop is set up. With a system that has such a high tdp it is quite possible. If you run from block to block without any rads in between it's quite likely that you're going to have a 6C difference, just as I had with my MM build. Placement of the sensors at the hottest and coldest point in the loop could easily show that large of a difference depending on overclocks.

Thats what i was saying aswell. When i get the new stuff i will put 4-5 sensors in the loop. That should give a more correct look at the whole thing.
post #24 of 37
I guess in Eggy88 case the deltas must be high enough to see a 6C temps difference, I'm not sure about those Bitspower sensors which is why I haven't installed mine yet.

The bitspower sensors should be OK. But we will find out once i get the Aquacomputer, will be trying to use 2-3 Bitspower + 2 Aquacomputer sensors.

Are these Bitspower sensors inline with the main water flow or are they recessed away from the main flow? I don't think the Bitspower sensors were meant to be in the path of the flowing water, that would be like the wind chill effect where things get colder that the ambient temps.

The first sensor is mounted in one of the holes on the 120mm Coolgate radiator. The radior has 4 holes, 2 on the bottom, and to on the front side of the bottom, if you look at the link is plugged in one of the hole that are plugged. Its after the res.

The second sensor is mounted using a T-block in the line coming out of the Gpu's.

OK, something just aint right here. The temps gradually became wors and wors. Now im at the point where even @ idle the difference is 10c+

At this point i know its not due to some temp reading errors. Using a IR probe i took a reading at the tube before the gpu's, and a reading on the tube after and there is almost a 10c difference, i can also feel the difference with my hands. By feeling on the block of the first card and the link going from gpu 1 --> gpu 2 its hot as ****. Idle temps on the cards are also at this point 60c+

Taking the computer down not untill i get the things i need to upgrade the loop. The GTX 360 and 240 are on the way, along with Aquacomputer A5, got 4 new links so will be going for paralell once i get everything. Untill then the rig stays off, dont want to run it like it is now.

How about your pump?

i can see a clear "turbulence" in the res and i see the pump spinning so its for sure working, that beeing said i have no way of seeing how the flow is, but looking at some small bubles it looks like it is OK, but not sure.
