0.6GPM flow is low or not? - Page 2

post #11 of 58
Thread Starter 
New idiea:
not buy D5 pump

buy new radiator
Change Alphacool Radiator XT45 to bigger

1. Alphacool Monsta 360
or
2.XSPC RX360 V3 Price is same 108Euro

When is not good flow and temp

+ change DDC pump to D5pump


Next pc brother AMD 6core

use ddc pump and xt45 radiator

smile.gif I have time to Monday change order.

you wont see a difference changing radiators. it will be a SMALL difference. the same with changing pumps. it will be a small difference.

what is your vcore under load?

Voltage 1.48V

5Ghz

8core

thats a lot of voltage. you should be looking at adding a radiator.
restriction (more pumping power), voltage (is quite a bit), rad space(for your rpm)

pick 2(or 3)
add another pump to overcome restriction, lower vcore, add another radiator and/or add fans/change them out for higher rpm fans

all just my opinions though. the only way i see to lower your temps.
what is your ambient temp anyway? this will say a lot also.

1: Run two pumps in serial, the DDC-1T has excellent power/performance, and is a good budget pump but with chipset and northbridge cooling on top of a CPU and GPU waterblock you're likely pushing the limits of a single DDC-1T. You don't necessarily need two DDC-1Ts, you could put a D5 and a DDC in the same loop, both pumps will have a higher nominal flow than what you'll be getting, meaning one wont bottle neck the other.

2: What are your ambient temps? A 3.120mm will run hot with that setup, but 50c is WAY too high for that setup which means one of two things, you have a high ambient temp or something is preventing it from cooling properly. I highly doubt your ambient temps are above 30 celsius or you'd be sweating profusely just by being the same room. Check to make sure your radiator is clear from dust buildup, that's going to be a huge factor for preventing your radiator from cooling properly.

3: Add radiators. I know I said that other rad should be cooling better, but even then a single 3.120mm rad is a little low if you're trying to push some overclocks like you are.

4: It's hard to tell just by pics but it seems like your rad is REALLY close to your chassis, meaning that may be obstructing airflow. You could either use some larger spacers, or drill 3 110mm diameter holes in the top of your chassis and push the rad flush with the chassis, allowing it to vent directly into the chassis.

I have not seen any testing on how accurate the Koolance flow meters and adaptor is, but seeing as 4 different sensors can be used without any sort of adjustment it would suggest that they might not be all that accurate.
The Aquacomputer models have very different settings for different models and even different settings for the diameter of tubing being used in the system.

The DDC1T is one of the lower power pumps for the number of blocks in the system though.

Koolance flow meter display is adjustable. It selects which flow meter automatically, and you use a little switch to select tubing diameter, it's just hidden behind the drive bay mounting plate.




The recessed switches and what not are hidden behind the drive bay mounting plate.

Ah, OK then I was totally wrong. Thanks for that, I had never heard that before.

It just seems surprisingly low flow.

It does seem pretty low.... OP might want to take his waterblocks apart to be sure something isn't blocking the flow, but then again he is running 4 different water blocks on it. I'm not sure which chipset and NB waterblock he's using but they can very between very low restriction, and the same amount of restriction as a CPU block. But then again AGAIN martins tests would indicate he needs 5PSI pressure drop to be @ .6GPM...

So yeah, OP you might want to drain your loop and inspect the waterblocks and what not to be sure they aren't clogged up.
