New Pump

post #1 of 13
Thread Starter 
I have posted in a previous thread asking if my X20 Rasa pump/res would be enough to handle my XSPC CPU block, XSPC RX360 and dual EK 6970 GPU blocks with EK Parallel bridge and have been told it should, but may have troubles. If it does not, I was thinking of going with this:

http://www.frozencpu.com/products/61...t_317_GPH.html

Will this work? I will have a couple of V3LN quick disconnects in this loop, but its not too big. Is the variable speed worth the extra money? Would I need anything else? I already have 2 fittings from the old pump/res combo.

The D5 is a fine pump for your loop and should run very quietly. The Vario version max speed "5" is greater than that of the Fixed speed version, stuck around "4" I believe.

The same D5 vario pump is $20 less and the same bay res-top is $10 less at jab-tech...

so you are saying the variable one isnt worth it? its not like the 35X that automatically changes pump speeds, right? I dont think the 35X will fit in that res either. Can you link them from jab-tech? i didnt see them, at least the res.

That res is for the D5 only. The 35X can use any normal res (no need for a res-top as it has a performance top stock).

The vario is worth it if you want the max speed out of the D5. If you planned on running it a little less, then it might not be worth it for you.

Would it be worth looking into a 35x over the 655 variable speed pump for my loop? Does anyone have any experience with ither of these directly and their performance/noise?

I cant decide which way to go lol. 35x and EK 250 advanced res or xspc res and 655 pump. I have the 800D case, so space isnt much issue.

If you utilize PWM to dial speeds up and down automatically, I would suggest the 35X. You may not need it, but it's a fair amount stronger than the D5s. D5's are actually a touch quieter full speed, but under automatic PWM control, you get silence and power.



I've used my share of D5s and DDCs over the years, and have a collection going now. The 35X is probably my favorite because of it's raw power and low heat dump and PWM.

I just really like the PWM feature, but it takes setting it up via MB temp/speed controls or speedfan before you get the real benefits.


The advantage of the D5s is they run cooler to the touch because they use a metal housing that transfers heat to the water better and they are run a bit quieter at full speeds, particularly with a thick acetal aftermarket top.

Both good pumps and likely strong enough for most systems out there, but the 35X is a fair amount stronger and PWM allows "Smart" pump control with nothing more than your existing motherboard and some software.

I am leaning towards getting the 35X and the EK 250 advanced res, but the 655 + xspc Res is in the running... i like the looks of the EK 250 better, but I am trying to plan out my loop to see which will fit best. I wish i could find more pictures of the 35x and 250mm res in an 800D to help me.

I'm running the D5 (Koolance flavor) in one of their dual bay res units, it has tons of flow and once all the air is bled out you can barely hear it run at all.

On a separate note, if you are looking to get as much flow as possible try to avoid the QDCs. I picked up 2 pairs and had them installed while running flow tests with one of Koolance's flow meters and found they took away quite a bit. The loop included one 370 cpu block, and a 570 gpu block, running one pump the QDC lowered my flow from 4.5 Lpm to 3.9 Lpm. The higher your system's pressure the greater they reduce flow. They are very convenient but they do restrict flow.
