Thanks REP+

That makes sense, once the flow circulates over time, the rads can't keep up cooling the flow. I see.. Interesting.

You would never see that in any real loop. Even with extreme flow rates of up to 9 Litres a minute water blocks still continue to cool ever so slightly better ... it is just a matter of diminishing increases. Flow rates that high only occur in CPU only loops with dual pumps.

Radiators are the same, cooling fluid doesn't need a period of time in a rad to give up heat. The fluid is an endless conveyor and the whole water volume increases in temperature. The rad doesn't care that the water is moving through it ... it is higher than ambient temp with air flowing through and gives off heat.
In fact higher flow gives off more heat because the water has less time to cool before it leaves the rad and so the overall temperature off the tubes is slightly higher along the full length of the rad ... higher temp means more watts given off to the atmosphere.

The only performance sapping effect from higher flow is the result of extra heat from pumps. At some point the small benefit of higher flow is outweighed by the extra heat created by the pump.

You are right in saying in this application you will never see the increase in temps due to high flow rates because we are limited on the amount of flow. But I have seen this effect on heat exchangers for a engine if your flow rate is too high the temps will actually increase in the engine because the water is moving too fast to absorb any heat. Now this is a industrial setting with very big engine and large pipe work and big pumps...

The increase in cooling performance from higher flow tapers off very quickly. Very few waterblocks benefit from high flow rates and the radiator (as someone else pointed out) just doesn't care as long as the water is flowing. I have more experience with DDC (as I pointed out) than with D5 pumps but I can assure you that both will dump heat into the system. I do not know if the DDC heat dump is worse than the D5 but you can feel the base of a 355 or 35x pump and it is very hot. As I have said I have put together a test loop with a D5 and the plate on the waterblock was very warm. I know there was no air moving through the radiator but regardless.

Anyways,

I think you have already heard enough to make your decision. I think there are many reasons for you to go with PWM.
  • The pump might last longer.
  • The pump may run cooler.
  • You should be able to find an acceptable sound level.
  • You can easily perform your own tests to see how much duty you need to achieve optimal cooling.
  • If you ever sell the pump it will be more appealing to buyers.

martinsliquidlab.org has a ton of information including optimal flow rates for specific waterblocks and tons of info on the pumps.

If I understand the site correctly at 21.3 watts of power consumption there is 17.76w of heat dump. Not a lot but it exists. Then again I could be misunderstanding the measurements but I don't have time to read the whole thing again.

D5's actually dump a significantly larger amount of their heat into the loop than DDC pumps. That's why you feel the base of the DDC get warm: it's cooled primarily by air, and is the reason why the Swiftech and Koolance heatsinks are so beneficial to pump life.

This doesn't really matter much until you have 2 or more pumps, at which point the D5's can add a not insignificant amount of heat to the loop, while the DDC's should add almost none.

I have water, intake air, and exhaust air temp probes and going from a single MCP35X to the MCP35X2, I didn't have even a tenth of a degreeiincrease in Delta-T, but I did get a flow rate gain, from 1.2gpm to 2.2gpm, and the pump heatsinks now sit around 5-8C above ambient instead of 10-14C.

That is good to know. I went from this

that is just a leak test but that was my pump. To this .

Mainly because of noise but my water temps did not go up because of the reduction in flow.

Those other pumps got fairly warm even at with them being a lower wattage than the 35x but the 35x at low PWM speeds doesn't get warm enough for me to worry about heat sinking it.

Although I would if there was enough room that the heat sink would not rattle against the bottom of my case I would put the sink back onto it. The pump is floating about 1.5CM (maybe less) from the bottom.

Uhm.. I guess I have to check play around with it once I have it setup.

How do I remove the 3 pin fan connecter from the connection?

Thanks for the info guys, REP+

HUH?

It will have a 4 pin connector with the RPM and PWM signal included into it. You can connect it to a normal header or to a splitter. I prefer having the pump onto the secondary CPU header and the fan splitter on the primary fan header. Both will get RPM monitoring but the PWM signal will be synced to the rpm of the primary channel and then duplicated at the PWM level to the second channel so if the fan receives 100% then the pump receives 100%.... You should get a pump RPM reading and a fan RPM reading but you will on have control over one or the other if running both off the CPU header. If you want the pump to be the one that is modulated then attatch that to the primary and attach your fan splitter to the secondary just understand the fans will only run at the % PWM duty that the controller runs the pump at.... When it says You get a separate fan RPM readout but the PWM will be synced to RPMS of the PUMP if it is primary or one of the fans if it is primary... since the pump is a separate beast and behaves so oddly. I may recommend you take someone elses idea and us the geiled mini video card PWM to normal PWM converter to run your PUMP... The RPMs will be controlled by the video card but that is your decision.

You have options and PWM is superior to the old school in so many ways but it hasn't completely caught along yet


If you are talking about the NON PWM version then the tach wire is just a monitoring device. You would use it with a high current old school fan controller to adjust the flow. Or you can run the pump at 5v (if it will start) 7v (should run fine) 12v which is normal... or 24v if it the model that can run 24v nominal... But I thought you where getting a PWM version... the entire reason we have been talking to you is to get you to convert to PWM!!!! which then you need both the RPM and PWM wire to control the pump... The 12+ and 12- go straight to those voltages and all of the RPM control comes from the PWM the motherboard PWM control decides what PWM signal to send based on the RPM feedback it receives.

givemedew - I actually am running w/o the heatsink on my MCP35X2 at the moment, and so long as I keep a decent amount of airflow around the pump, it never warms up enough to worry me. IR Thermometer says the bottom ranges from ~18.9 to 25.4C in a room @ 16.5C.

Airflow is critical, the heatsinks (and fan mounts for the heatsinks) just enhance the cooling. If you can't fit one, don't worry about it; just have a fan blowing across it.

It will have a 4 pin connector with the RPM and PWM signal included into it. You can connect it to a normal header or to a splitter. I prefer having the pump onto the secondary CPU header and the fan splitter on the primary fan header. Both will get RPM monitoring but the PWM signal will be synced to the rpm of the primary channel and then duplicated at the PWM level to the second channel so if the fan receives 100% then the pump receives 100%.... You should get a pump RPM reading and a fan RPM reading but you will on have control over one or the other if running both off the CPU header. If you want the pump to be the one that is modulated then attatch that to the primary and attach your fan splitter to the secondary just understand the fans will only run at the % PWM duty that the controller runs the pump at.... When it says You get a separate fan RPM readout but the PWM will be synced to RPMS of the PUMP if it is primary or one of the fans if it is primary... since the pump is a separate beast and behaves so oddly. I may recommend you take someone elses idea and us the geiled mini video card PWM to normal PWM converter to run your PUMP... The RPMs will be controlled by the video card but that is your decision.

You have options and PWM is superior to the old school in so many ways but it hasn't completely caught along yet.


If you are talking about the NON PWM version then the tach wire is just a monitoring device. You would use it with a high current old school fan controller to adjust the flow. Or you can run the pump at 5v (if it will start) 7v (should run fine) 12v which is normal... or 24v if it the model that can run 24v nominal... But I thought you where getting a PWM version... the entire reason we have been talking to you is to get you to convert to PWM!!!! which then you need both the RPM and PWM wire to control the pump... The 12+ and 12- go straight to those voltages and all of the RPM control comes from the PWM the motherboard PWM control decides what PWM signal to send based on the RPM feedback it receives.

Here's the picture of the pump that I have currently but going to exchange it for the speed control version. Regarding the fan control, there is only 1 pin attached so I take it it's just an RPM monitor. How do I remove that 1 pin connection so when I get my new pump I can install a mod kit to the pump.
