Hi,

I have three rads i want to use, two gpu blocks and 1 cpu block. Wonder will the EK XTop Revo D5 be strong enough or maybe the Koolance Pmp-500 be better choice though at 50 db?

Thanks.

ps: want to connect my bitspower multi250 res directly to thr EK Revo D5 if possible ,

thanks.
 
You can use many different pumps for such a loop. The brandnew alphacool 755 for example, or the silent Alphacool ddc 310

the koolance pmp500 is quite noisy

All of them have more than enough power !

Yeah but i read its like two pumps in one its so powerful.

Maybe by connecting the res directly to the pump it may soften the sound. Also, you can always pick up a sound damping mount for the pump. I think my pump came with one, but it's a square piece of foam that sits between the base plate of the pump and your case.

That's a good idea but for the fact I'm not sure a top res combo exists for the pmp500 and bitspower res..
 
I think I have one of those. Would prefer a top that's fitted straight to the res instead. Looks nicer.

About the noise yeah it's crazy I've heard on YouTube. Would want an rpm controller at the least. At least it's powerful enough to surpass the restrictions on the blocks.

Thanks.
 
Only trust the D5. A single one will do it, but it will be a struggle. I'd say go two D5s.

DDC pumps are noisy and annoying. Their DB ratings don't tell you how high-pitched they are. D5's make a low rumble, DDCs whine.
 
The pmp-500 is a ddc? Read it was a modified D5. Could be wrong. Anyhow already bought an EK Revo D5. Added up all the restriction values and they basically cancel out the EK's head pressure of 3.9 psi and it's rated at 40.5 db whereas the pmp-500 is at 49 db. I could get another Revo and link them together with a double ended top. Only wish I had bought a parallel bridge connector instead of the serial one I got as it would have halved the gpu restriction. Maybe still time to RMA..

Thanks

No, the pmp500 is not a D5 derivative with its external coil design which is evident by the heatsinked body ie. it dumps heat into the air rather than into the loop like the D5. There are internal pics at Martins. Its design is closer to the VP755 with similar external coil design and impeller setup, ie. they both are more similar to aquarium pumps. As for your head issue, I think its a lot cheaper to go 24v than dropping another D5 in there. The question is can the Revo do 24v?

The EK website says their PWM pump is a modified xylem design, I imagine their vario is the unmodified version. Either way, the vario pump is listed to work between 8 and 24V DC, both on EK's website and in the datasheet (The one you want is "SS-07R2 D5 Plastics" I think), so it should be fine. Just be aware that in unrestricted loops it can pull upwards of 33W (vario) and 40W (strong). ;)

Xylem = Laing's new name. And what a strange name... smh.

Btw, the reason I said to check if it can do 24v is because not all D5 receive a gain. I don't stay on top of what rebranded D5 is or what is what, but going back 24v is only critical in achieving the most performance with a Strong.
