Help with a new custom loop build

[Flow252]

Hey everyone,

 

I'm looking for some input on the my first custom loop and if I'm being honest my first custom PC.  Here are the specs:

• Ryzen 5900x
• 3090 Founders Edition 
• 64 GB of 3600 MHz Trident Z Neo CAS 14
• Asus Dark Hero
• Corsair AX 1000 Power Supply
• Corsair XD5 Pump/Res Combo 
• EK Velocity Water Block
• Corsair 3090 Water Block (Currently not Installed)
• 2 45mm AlphaCool V2 Radiators 
• 6 120mm Corsair QL Fans
• Lian Li O11 Dynamic 

First off, the goal for this build was something as balls to the wall as my budget allowed and I feel really fortunate that I was able to get all these parts. I also really wanted it to GLOW with RBG and dabble in some light overclocking.  With GPU blocks being pretty scarce for Founders Edition cards, I went ahead and built the PC with just the CPU in the loop.  After several weeks of gaming and work on the new bulid these are the current thermal trends I've documented with the CPU at stock settings.

• Under full synthetic the CPU reaches temps upwards of averages of 65C with peaks around 68C boosting to between 4200 and 4300 MHz. The coolant temp is measure about 28C.
• While gaming, max everything and anything, the CPU will reach up to 75C boosting to 4800-4900 MHz (usually stays around 4850 MHz), the GPU with the FE cooler is around stays around 70C +/- 2C boosting to 1900-2000+ MHz but the coolant temp in the loop I've seen go as high as 35C

The current fan set up is the bottom rad/fan combo is pulling air in and the top combo exhausting. My questions are the following now that I have received my GPU block. 

• Do you think the loop has the capacity to handle adding the GPU into the loop without overwhelming it?  Also, should I expect to see better cooling results that I am currently getting from the stock cooler?
• Are these temps for the CPU expected and is there any head room for overclocking the CPU and even the GPU from your experience?

One the main reasons I am hesitant about just testing the current configuration by adding in the GPU was the comment Steve from Gamer's Nexus made on the tear down video of the 3090 FE where he mentions they get weird thermal throttling after reassembling the card with the stock cooler.  I realize that QLs are not the best fans since they are not SP optimized but I love how they look.  However if I am unable to get the results I want I might consider changing them to some powerful Noctua SP optimized fans in the future. 

 

If any of this is unclear please feel free to let me know and I'll do my best to clarify!

 

Thanks for any help!!

so with the custom loop that i had, i was using a strix 1070ti overclocked and a r5 2600x also overclocked with a 240mm and a 280mm rad.  Cpu temps never went above 50c and gpu never went above 45c.  Now i do know that we are talking about different components here.  I would possibly switch out the fans.  I know you want RGB so i would probaly go with the ml pro rgb.  They are better at cooling and better for rads as well.  Fans do make a difference in temps.  Otherwise you should be fine to add a gpu into your loop.

Why those radiators? Pro is the multiport design which is great for placing fill and drain ports and bleeding as well but the Con is their mediocre performance.

 

I'd personally change to a set of better fans with low revs, high static pressure and low noise. But ultimately the coolant temps are okay but not excellent considering its CPU only. But then again we don't know ambient temps. Absolute temps are of little interest, ΔT over ambient is. If your room has 24°C then the coolant temps are good, if it has 19°C then it should be better.

 

Your components run pretty hot and your CPU has a small IHS and even smaller chiplets underneath. That inhibits heat transfer. Considering the PBO boosts your CPU just boosts higher until it reaches some predefined limits which then in turn means more heat.

 

You're missing info on radiator size and the fan config. With 6 fans I assume 360 rads but then the side mount is empty.
