Is this to much for my D5 To Handle ?

I don't know how you got your numbers, guys, but from running single loop vs split loop my water delta was about 2C difference at full load, it could however be related to how much radiator surface I'm running though.

The amount of radiator surface doesn't let you get temps colder so much as it does a better job of heat removal = thermal transfer efficiency. This means you can run a higher clock with more voltage and still have about the same temps under load or reduced temps at the same settings under load. Helpful if doing a heavy CPU intensive bench such as Cinebench or a torture test for stability. The biggest benefit is obviously with a better thermal efficiency, you gain some stability overall, not a world of difference but enough you'll notice when pushing things hard.

I can't read it, too small, host the full size shot on the TPU image host.

I personally like running dual loops when cooling a CPU and two GPU's. For a single GPU plus CPU I would go with one loop (maybe two pumps in serial). But that is just me. I really like having a rad before my CPU and then before the GPU(s). The difference in temps is probably not that much. I have not tested this myself - just from what I have read.

What is ambient temps? What TIM did you use?

3/8 or 1/2 hose and fittings?

Ambient 29*C

XIGMATEK PTI-G4512 thermal grease with gold grade thermal matrix filler particles ( About to replace with Shin-Estu X23 7783D )

1/2" x 5/8" Hose and 1/2" High flow barbs

A cheap hippy block XD

Buy a better block, sell your third radiator. Stay cooler.

or keep the rad, and buy a better block...

It was already determined my block is fine

I have a water cooling setup and I'm trying to figure out if I need to add a second pump in the loop and is my D5 at its limits. I'm running 3x 240mm rads, CPU Block, and soon a EK GPU block with a Swiftech MCP655 & Cylinder Res. The reason I ask is because yesterday I added my 3rd rad into the loop and oddly enough temps went up some then with 2x 240mm

What you're seeing is a decrease in flow through the CPU block You may see a decrease in overall temps after it all stabilizes (overall heat dissipation capacity has increased).

Bottom line, you will see an improvement with a second pump, that's a lot head loss with 3 rads.

It indeed has decreased but i can tell flow has slowed after examining water in the res. Can i use a MCP350 DDC-1T as the second pump as a second D5 would be expensive

Y the loop through the radiators to gain flow. Split down to two 3/8 and run one each through a radiator.

What do you mean

Yea the D5's aren't cheap. The DCC-1T should get you another 0.5-1.0 GPM in-line with the D5. I flow tested a single D5 and a dual D5 setup with some fittings to mock head loss. Got about 2.2 GPM with the single and 3.5 GPM dual. The DCC-1T has a curve fairly close to the D5.

Aka, should do the trick...

Were do I add the second pump or does it not matter

I'd be inclined to put it either before or after the D5 ...depending on your layout.

older image but its still almost the same

That's tight. Is the pump behind the rez? I'm not familiar with that reservoir...

 

[Durvelle27]

Yes the pump is behind the res and the res is a Thermaltake SR100

One thing I can add is that a larger size res will help stabilize temps when doing a long bench run.
It takes x amount of heat energy to heat up x amount of water/coolant and the larger the res, the more heat required to heat it up. This is good from a temp standpoint of keeping temps in check and not allowing the entire cooling system to heat up, esp if it's not removing the heat properly. I use a 2.5 Gal res for my benching and it's always helped me to hold some good temps, even over the course of a longer bench run. The OP's setup is all contained within the case and while it will work, it doesn't work as well as one like mine does overall - Mine is mostly external including the pump.
The res itself I had to make from a water container I bought from Wal-Mart and modded it for use with the system.

I am still running this setup. With a few minor changes. Closed loop, Pump-->CPU-->GPU-->Res.

Same PSU, block and pump as mine..... You been raiding my parts stash?
