PC still hot with custom loop

[nuclearharry]

So i just built my first custom loop in the enthoo primo i have x2 980ti's and a 6700k "stock" being cooled the loop is d5 pump/res combo running at 100% a parralel terminal x2 480mm radiators 1. ac monsta and 1. ek coolstream both in push pull and the ek supremacy evo cpu block.

my cpu is running at 68c while gaming and the gpus are at 60c

which seems too high for a custom loop with x2 radiators that big i had aios on my gpus and cpu before and they did a much better job despite having alot less surface area

anyone have any idea what could be causing it to still run so hot?

thanks

Those temps aren't anything to worry about. Maybe the pump isn't strong enough?

[nuclearharry]

they might not be super high but i havent OC'd the cpu yet either i did ask if 1 d5 would be strong enough on these forums before and everyone seemed to think it was more than enough just a little gutted £600 on a custom loop and its hotter than before

Reapply thermal paste and see

This dude dind't quote ytou so Imma do that...

radiators are bigger so i guess its your pump. crank up its speed?

yeah i have the pump running at 100% i just took the cpu block off and reapplied thermal paste still the same temps i had all the components in a define s before with a 280mm and a 260mm rad and a serial terminal and was getting slightly lower temps than this i figured switching to a bigger case and radiators and a parralel terminal for better flow would help but obviously not lol

just one pump? something in your custom loop must be less that your previous AIO and its not the radiators, unless the rads have less surface area in their fins

yeah just the one when buying the parts i asked on this forum if one d5 would be enough and everyone said it would be plenty especially at 100%. just dont want to drop another £100 on another pump and it not make a difference

Is it possible the pump & res combo is dumping GPU heat into the CPU?

Why do I need to quote him on HIS topic when he already gets a notification if anyone posts?

the loop order goes from the pump/res to the gpus then to the top ek 480mm rad then cpu into the bottom 480mm rad back into the pump/res i would ahve thought the 480mm rad between the gpus and cpu would be better

I would think the same but this appears to be the difference with your AIO. Its also possible your AIO had good radiators with higher fin surface area

the ek is quite high fin density more so than the AIO's i was using and the monsta isnt really high fin density but is 90mm thick

That may have been confusing, I quoted what he posted at the top and told him to quote and quoted you at the bottom. So basically I was telling him to quote and not you

[0ld_Chicken]

what fan speeds are you using?  What speed is the pump running? (op said 100%)

 

Can you post a picture of the loop?  That can be a huge help with fixing loop problems!

If the pump is definitely running at 100%, then it could be something to do with your thick rads and may be a flow or restriction issue and/or fan speeds. The fact you had the same loop with different rads before running cooler is perhaps suggestive of this. If you've already tried re-applying TIM, then that isn't the problem. That pump should be MORE than enough, it shouldn't need to run at 100% to keep things cooler. And yes, post a picture...

[Mick Naughty]

The CPU block is port specific and even some gpu blocks are made that way but with the serial block on there that should be fine.

 

Using a d5 combo with 7 blocks and 3 rads,  temps could never get that high, pump at 40% and fans can't get any lower then 40%. Even threw 3 more rads on the loop atfer I was worried about having to get an additional pump. 

[Mick Naughty]

Did you spend time tilting the system every direction to get the air out?

[atomicus]

Daft question perhaps, but I presume everything is flowing correctly and in the right direction... i.e you haven't gone 'in' to an 'out', or vice versa?

I think You need one more pump end set dual pump in series for more head pressure.

What is your coolant temp?

 

 

[stealth80]

make sure it's bled, what fans you using?

I Agree

 

The D5 pump has a Head Pressure of 4m I think.

Your loop sounds quite intricate, the more fittings radiators and twists and turn you add to your loop the greater the resistance.

This may be the pump simply not moving cool water around the loop fast enough.

The AIOs would perform better because they had individual pumps and Radiators.

 

I had a Similiar setup and Ran a Swiftech MCP35X2 to get enough pressure.
This has a Head pressure of 8-9m
