I don't see why not other than being careful when filling the small reservoir unless it's already prefilled.

I wouldn't add much to those AIO pumps since they are exactly that, low powered with just enough flow.  The EVGA HC blocks are known to be a bit restrictive as you'll want nothing less than a more power premium pump running such a block with a full custom loop.

The main reason I am doing it is to use the Eisbaer pump as a second pump for safety after seeing one of the GPX pumps die.once i get another 240mm radiator I am going to remove Evga CLC and just use the custom loop. Everything I read says the Eisbaer is a DC LT 2600 pump. I understand what your saying about saturation but every person i have talked to says the rule of thumb is 120mm rad for each component and to double if overclocking. which is why my goal is 240mm for gpu and 240 mm for cpu and then later purchasing a reservoir pump combo which all of this is to prepape for 70c RTX cards

Could someone suggest a good pump. I know the ones I am using are the weak link.

Thank you for the pump recommendation. i was going to go with the Eisbaer Extreme for the D5 pump but it was to big for my case.
For now i am going to use both Radiators on the Gpu see what happens i can always remove one if no improvement. i just felt the gpu should have at least a 240mm.
Well i managed to put
240mm rad in top of case push/pull
120mm rad Rear Exhaust push/pull
Eisbaer DC 2600/Block Reservoir
Evga CLC 280mm for CPU in push/pull
140mm Air Flow fan lower front
 
And of course i forgot to buy a fan controller or splitter for PWM
of course the only thing in my junk bin is an old Cooldrive6 but  it only does 3 pin, plus i am not sure if i trust its kinda old loke me

i hate to pay it but i think i am going to go with the corsair link. the last 4 years i used the H100i and i never had any issues. Worked great with my hardware. the biggest frustration i have had with this project was losing the Corsair link it was great for changing profiles and i would use it to record if i was troubleshooting or benchmarking. I screwed up buy selling the H100i yesterday to a friend i should of used it as a fan controller. Oh well live and learn. If i did my math right the only 2 headers that could be over an 1amp would be CLC and GPU Pump
CPU Fan Header (Evga CLC)///Aux Fan Header (Gpu Pump)// Eisbaer Direct power///Fan 1 header 2 Ml pro 140 Front rad///Fan 2 Header 2 ml pro 140 Inside front rad///Fan 3 header 2 Aurora Pro///Evga CLC pigtail 2 Aurora Pro////2 Corsair SP ran direct with resistor to power supply and 140mm air flow direct powered the only 3 i can not control Using an app Remote System Monitor on old Note 3 for real time monitoring pretty cool app once i realized a dollar donation removed adds. Just ordered commander pro plus it will be nice to play with the leds on the ml fans. I have to say these forums are great most people think i have 3 heads the way i spend just as much time screwing with my computer as gaming.Thank god the wife likes shoes and handbags it helps when making impulse purchases

My local computer store is going to hopefully get more of the Octo back in stock much cheaper then quadro. worse case looks like i can order one from canada. Thank you very much the Octo looks perfect for what i want. i am trying to avoid giving ups a drive bay.
I think the Octo for fans corsair link for the ML fans i have will do the job

Right now the only place I can find the octo in stock is a company out of Canada but they want like $70 just for shipping. Which is more then the controller its self. So I am trying to be patient. Not my best quality. I am loving these temps. Gaming my gpu is staying between 32c and 35c. Now my cpu is the hottest device in the case because of the Evga CLC but that still averages between 35c and 41c . I cant wait to add a DC5 pump w reservoir and XPS cpu block

That is a nice offer, a213m! I like the info grid you have in the case. :) +1

Well Patience paid off ModmyMods came through for me. The OCTO is crazy for the $55.00 they charge and for another $10 i was able to run my corsair products without a separate hub or Link or commander pro. Have to recommend to any one if they need PWM fan control will work for 3pin fans but just monitoring or Off function.
So now i have a few days of figuring out the software(work in Progress) to keep busy till next week then its A Next D5 pump with 280mm rad and i will be able to remove the Evga Aio and when i finally upgrade components all i need is a new gpu block and possibly cpu block. Thank you guys so much for opening my eyes

Honestly i have been thinking about the Aquaero 6 but i am not willing to give up the space.in order to have a drive bay free i would have to give up my front mounted 280mm rad, But i was told buy tech support that as long as i hook it up and activate it once, that i could remove the screen from the Aquareo 6 and use it as a hideaway. the screen is needed for for first activation so it registers as an XT and not an LT. With me buying the D5 Next i dont think i will need the Aquareo 6. Between the Octo and the electronics of the Next D5 i believe i will have close to the same control and monitring,but i love the idea of the remote function of the Aquareo 6.
Bells and whistles are cool. Lmao

The D5 Next is PWM controlled which the Octo has fan curve,PWM%, and temperature control. Would their be any benefit to voltage control? One i get the D5, i plan on removing the (Eiswolf and Eisbaer Pumps and Evga CLC) which at that point everything i have will be PWM control. Thank you for the input Maybe i should read the manual for AQ6 XT. Honestly i am still kinda figuring out the Octo.Once i am done with this i plan on using the Alphacool pumps for a media center build so the AQ6 might be the option for that build i know those pumps have voltage range from 7v to 12v.
I think this week i am going to pull Evga CLC add the 280mm rad so i can baseline everything so i will be able to see what benefit the  D5 Next gives me vs the DC2600 LT pumps. I have to laugh after spending 25 years in the Auto Industry of the similarities between Automotive and Computer Modding. I just learned that the problem i had with the Eiswolf is that they had three revisions. First one has a flat backing plate (no cutouts) incorrect screws caused alot of GPU's to fry. 2nd revision had cutouts in backing plate and incorrect screws( workable)( kit i have) 3rd revision had backing plate with cutouts and proper screws.Only large moving models saw 3rd revision. It appears they also went to great lengths to make sure none of it was documented. Makes me wonder if we might not see safety recalls on water cooling parts in the future. Lmao 

i completely agree on the pumps but would rather use them on some old hardware then to sell them or throw them out and they are still better then stock cooling solutions in my opinion. Thanks again for the education.I will stick with the Alphacool Rads but really looking forward to getting the D5 Next installed just waiting till i get paid then i get the fun of finding one in stock. My local computer shop sells out within hours 

Thanks for the link you saved me some time. Those are the way to go.Does reservoir size have a direct effect on cooling?

Nope.  Buy the right size for looks.  Just consider the fill port area and a drainage might need some spacing.
