Pump Selection Sanity Check
 

I'm building a new setup for my A64 3000+ and I'm still trying to nail down which pump to get. I've already decided on a 12v pump and I'm building the system more around quiet cooling than absolute performance. With that in mind I ran a few numbers to find out what the performance trade-offs were for each of 3 pumps. This is my first attempt at the exercise so let me know if you see anything blatently wrong.

Based on what I calculated no pump is a bad choice but I'm leaning towards the CSP-Mag for Price, quietness, and performance

Equipment list so far:
BIP III
Apogee
MCW60

Using the numbers I could find for the parts above, I did the analysis to see what my expected Water-Air temp delta would be for a: MCP350, MCP655 (#1-#5 setting), and CSP-Mag.

System resistance curve fit: PSI Drop = 0.3324x3 - 0.21x2 + 2.1156x - 0.704 where x is the flow rate in GPM. Number includes an additional 10% resistance for tubing

Rough estimate of 100W for the CPU and 50W for the GPU.

MCP350: 1.33 GPM, .037 C/W CPU, .039 C/W GPU, .032 C/W BIP III, 8W pump
CSP-MAG: 1.07 GPM, .039 C/W CPU, .040 C/W GPU, .034 C/W BIP III, 8W pump
MCP655 #5: 1.61 GPM, .036 C/W CPU, .038 C/W GPU, .031 C/W BIPIII, 15W pump
MCP655 #4: 1.41 GPM, .037 C/W CPU, .038 C/W GPU, .032 C/W BIPIII, 14W pump
MCP655 #3: 1.15 GPM, .039 C/W CPU, .039 C/W GPU, .033 C/W BIPIII, 6.5W pump
MCP655 #2: 0.89 GPM, .042 C/W CPU, .042 C/W GPU, .035 C/W BIPIII, 4W pump
MCP655 #1: 0.66 GPM, .046 C/W CPU, .046 C/W GPU, .036 C/W BIPIII, 2.5W pump

Interesting. Nice work!

Re: Pump Selection Sanity Check
 

Check out the review where they measure how much heat dump each pump does.

Where did you get the data for the BIP three?

My approximator is being updated as we speak...
Will post URL soon.

Re: Pump Selection Sanity Check
 

Great JoB! I see your data confirms my choice of the Laing D5 as fair one then!
Thanks and quiet wasn't my concern.

Re: Pump Selection Sanity Check
 

I pulled the BIPIII numbers off of the first page of the "How much Pump is enough" post. The numbers are actually for a thermochill 120.3 but they work in a pinch.

My pump heat dump numbers probably aren't too acurate as I did them last and wasn't concentrating due to my wife talking trash about me being a nerd.

Here's a look at the pumps used which gives a good insight into physical size.......from left to right

Eheim 1260>>>Eheim 1250>>>Eheim 1048>>>Eheim 1046>>>Laing D4

Here's a Laing D4 Pump along side the tiny Laing DDC-12v
http://www.coolercases.co.uk/images/Misc/d4_ddc.jpg

This is the new Laing D5 which is exactly the same physical size and shape to the Laing D4 apart from offering an inbuilt rheostat to control flow rates and being black in colour.
Set on No5 (highest setting) the pump is very very quite though still gives a little noise where as set on No1 (lowest setting) i would say the pump is virtually silent.
Set on No4 it would seem noise level to be similar to the Laing DDC

Cheers ElMoIsEviL !!!!

Whilst I prefer the pump review from that French site as it included watts added to the coolant, I can use these figures to derive PQ charts for the Maze4 chipset and GPU coolers.
Which will have to do until I can convince RoboTech to do a proper test of them.
