After much thinking I decided to go custom from the start and dont waste my time and money with kits!

After hours of reading I chosen this so far:

CPU: D-tek FuZion
GPU: EK 1900
RAD: PA120.3 Thermo (with nexxus fans or panaflos, depends what available)
HOSE: masterkeel 7/16

I belive is the best I can get (without spending another hundred quid for names and 0.01% performance increases) :p


So here I am now thinking what pump I should get :confused:

What you guys suggest for a pump?

Laing D5 (the swiftech branded MCp655 I think) vs Laing DDC ultra (18w) with Petra's mod top.



Any vets using them or something better I d appreciate your input :)

Laing DDC ultra (18w) with Petra's mod top or plexi top i have both and are the best pumps for the job m8 :)
 
I used an Eheim (1250 ?,i think)

Extremely quiet you had to touch it to check that it was running.

Either the DDC ultra or pro will do fine with that loop prefer the alphacool top myself.
 
well well well,

I ll add a Laing 18w + Petra's top to begin with.

However, the thing that really made me consider the DDC from the start was the fact of constant high head regardless the loop. Something the D5 lacks.

Anyhow, the only thing that matters is the temprature reading on my probe once everything is in place :D



edit: You guys from experience with water whats your opinion on Nylon vs metal barbs?

Thanks for your input!

Valid point, how about corrosion and stuff? or it will take more time than the life span of the system to go bad?
 
duh, forgot the most important thing :p

Smoothy Water or MCT or something else?

I know you can submerge a live fan into smoothy and will keep going.
 
Sorry to steal this thread but would a Laing D5-Vario (1/2") , be enough for :

Thermochill PA120.3
apogee gt cpu block
dangerden 680i chipsetblock
EK 8800gtx block? :D
 
Remembered reading this ages ago, awesome thread with the following summary:

I still hold great confidence in saying that the "ideal" water-cooling pump, that is a realistic and feasibly built possibility (based on the MCP600), would be:

6-8mH2O (20-26') of peak pressure head
12-13LPM (3.2-3.4 US GPM) peak flow rate
25-30W nominal power draw (when in operation)
12VDC
Separated Magnetic Armature design (~16-20W of heat added to the water)
Centrifugal pump

Any pump which has specs stronger than this starts to take strides backwards in terms of offering better performance.

Those who know, know who Cathar is and how painstaking his work is - compare your pumps to his recommendations and draw your own conclusions ;)
 
Cathar's statement has been updated elsewhere to say that the DDC with aftermarket top is the pump of choice... s'on XS somewhere...

Waterblocks, given the pumping power available, are about at the limit. There's no big gains left any more. There are refinements (such as the G7's larger cooling patch to service IHS capped CPU's a little better) and small improvements (G7's lower pressure drop, more even internal flow distribution and increased fine jet density), but overall in terms of thermal transfer efficiency per unit of pumping power, it's pretty tight.

For radiators, I put everything I knew about waterblock flow and lots of added analysis and emperical testing on fan flow and efficiency into the PA design. I specifically targetted making the radiator super efficient for lower powered fans (60cfm and less) 'cos I couldn't see anyone in the industry who was targetting that area. Turns out that the PA radiators still kick butt up to 100cfm fans too, if you can stand the noise.

For pumps, I'd been pushing hard both on-line over at Procooling, and behind the scenes with a number of industry players. While I never spoke directly to Laing, quite a fair bit of feedback and suggestions did flow from me to them through different channels, and now we have the Laing DDC+, which if you read my specs for the "perfect pump" over at Procooling, the DDC+ is almost exactly what I was pushing for. With the after-market 1/2" tops, the 18W DDC+ is exactly what I ever envisioned the ideal PC water-cooling pump to ever be.

I must have tested dozens of fans, and the Yate-Loon/Nexus/Tricod-Science clones always came out on top for low noise and pressure and performance at low noise.

After testing and frustration with 1/2"ID/3/4"OD tubing, I researched and found 7/16"ID/5/8"OD tubing to be the near perfect tubing solution.

I guess what I'm getting at is after years of researching and pushing, I've seen pretty much every single one of my goals being reached through one avenue or another.
