Better temps with Better Pump??

post #1 of 13
Thread Starter 
Im thinking of getting a better pump if it helps my temps..currently ive got a d-tek db-1 pump...same as that danger den pump (the really cheap one, does 500lph and 2.0m head) At the moment ive only got a cpu loop with a t-line..with say the Laing D5 vario pump...will i get better loads...right now as im typing its quite warm in my room, not sure of ambients exactly but with my sandy at 1.75vcore im idling right now at 35C..loads at 40C..so would a better pump with more LPH and more head pressure give me better temps....also i will soon be getting a res and an EK chipset block, which are hardly restrictive at all, so it shouldnt make much difference..a degree or 2 at most.

i doubt you will see a DeltaT worth the cost of a new pump with only a CPU loop. consider buying a D5 when you add your GPU.

Have to agree with Chiel.
As has been noted in other threads, flow rates over 1-1.5 gpm don't affect temps to any significant degree.
Last night I decided to plug in the DC converter on my pump which allows me to change the voltage from 12 up thru 24 volts and while I noticed a significant change in flow rate, my temps pretty much stayed the same while running Orthos smallffts for 10 minutes at each voltage.

If you have a free flowing CPU block like the Fuzion with-out nozzles I doubt you will see much difference, if you have a jetted block you might...You might be better off getting a bigger rad or higher cfm fans...

Is that with a high v-core and heavy OC? That will make a difference..I like to keep my flow over 2gpm, but at the least 1.5gpm so my flow wont turn laminar...

How do you like that pump? I'd love to do 2 of those in series...

OC is 3.6 with a vcore of 1.36 vdroop.

So far really like the pump, only put the converter on last night to see how much difference it would make and as far as temps the only thing I noticed was that at 18v, my load temps would constantly flicker between 42 and 43, all other voltages were pretty much 43 stable with an occasional 1° up or down flicker.

My dual bay res on the other hand which has about 1/4" or less of air space got extremely agitated, enough so that on 21v+, occasional air would get sucked thru into the pump

Thanks...I've got to get one of those.....Thats shaping up to be a killer little pump..I only got a 2C drop adding a second 18W DDC back before they were de-tuned...But really a lot is going to depend on restriction and ambients and OC's and all that...

Thats how my res looked with a single old 18W DDC...

hmm, just noticed you use an EK supreme. damn, i cant believe you put that and a DB-1 in the same loop. yeah, you will probably see better temps from a D5 then.
you could also consider selling the EK and buying a DD MC-TDX.

Yea i know its apparently a very restrictive block..so maybe a better pump may benefit me..but is the DD MC-TDX better than the supreme or are you suggesting it because its cheaper than getting a new pump??.

Yea its an ek supreme so its pretty restrictive...also ive got the swiftech MCR 320 and i think its a pretty decent rad..but yea i think i definitely need more fans...ive only got 2 on it at he moment and they are the stock Thermaltake fans that come in the armour case.
