First Time Custom Loop Experiment! Advice!?

[SnakeDoctur]

So I'm currently running an i9 9900k @ 4.80GHz / 1.275vcore and an EVGA 1080 Ti SC2 @ around 1900MHz / stock voltage.  The pump on my Fractal Celcius S36 I had on the 9900K appears to have died.  I decided to take this opportunity to dip my toes into the custom-loop waters.

 

Will this prebuilt kit https://www.ekfluidgaming.com/ek-kit-a360g be enough to cool a 9900K + 1080Ti?  I'm having a hard time reading EK's literature to find any "Rated TDP" for this system.

 

(shoutout to Fractal Design's support team.  Provided them a proof of purchase and they OVERNIGHTED me a brand new Celcius S36 cooler.  Which I plan to just EBAY since its a brand new, unopened product)

Take what I say with a grain of salt since I’ve never done a custom loop, but I would go with standalone rads for each the CPU and GPU

The 360mm rad that the A360G comes with should be plenty enough to cover a 9900k and a 1080ti, assuming that it has respectable airflow through it.

Thanks for the info man,  I'm certainly hoping so.

WORST CASE scenario it looks like their Liquid Gaming Expansion Kits are relatively cheap for an addon 240mm rad if needed.

It really shouldn't be necessary under any normal conditions, but it is an option I suppose.

I'm running a 4790k (1.2v 4.5 all core) and a 1080ti on a 280, in a case that has "good enough but not fantastic" (rough quote from Steve over at GN) airflow (Evolv X) and I'm positive that I have overhead in my current loop.

Add another ran. Unless you like more fan noise and speed. 

360 is never enough.

What kinda CPU and GPU temps do you get w/ that loop?  My 9900K is a bit of a dud (it does 4.80GHz @ 1.270vcore all day but requires 1.310vcore just to do 4.90GHz so 5GHz is realistically off the table).

Well...the EK A460G Kit is already in shipping.  I think I'll try my luck with this, first, then look at expanding w/ another 240mm if i really need to.

 

This is only the 2nd PC I've ever self-built and now this will be my very FIRST time doing a "custom loop" so I wanted to go with this premade kit to keep things as simple as possible.

 

If I end up liking it I can go with a more traditional loop next PC build a few years out from now!

 

Thanks for all the tips guys!  Appreciate it!

Under a real-world workload, my temps top out right around 50° ΔT over ambient with my front panel on. Removing the front panel can knock that down ~5°, this is with a fairly conservative curve however, with my fan curve only hitting 100% at 79°c (which during winter months, I rarely hit)

 

Under Synthetic load, I can push it to ~70-80°ΔT over (you'll have to forgive me for that range, it's been a number of years since I pushed her that hard), but that's after an extended runtime of something intense such as linpack. That would mean numbers that throttle during summer months

It's been a hot minute since I monitored my GPU temps (pun possibly slightly intended), but I remember them being in the mid-60°'s for the core, slightly higher for the VRM's, and that would have likely been tested with Destiny 2, some time around the Forsaken expansion, Similar ΔT as the CPU.

When it comes to a dud, I can say I'm there with you, in a little bit of a strange way. I've been stable at 1.2@4.5 (which is a slight undervolt with a slight overclock from what stock tries to push) all core for several years, but I can't get 4.6 stable at anything that I've tested, clear through to 1.295v, and I'm not really comfortable going any higher,

K well this sounds rather promising.  9900K definitely pulls alot more power than a 4790K but at the same time I'll have a 360 rad over your 280.  Is there ANY chance I could bother you to run a quick stress test (literally 1 or 2 minutes) and monitor the peak wattage your CPU pulls? (via HWMonitor or HWINFO). 

 

I know my 9900K pulls around 225W fully-synthetic and around 150W when playing a stressful my game (but generally closer to the 100W range).  And my 1080Ti seems to pull around 250W max as well.

 

Thanks again my dude!

I'm not home at the moment, I will when I get the chance though.

From memory, I remember linpack pulling a max of somewhere around 91w, I don't have number on the GPU. I don't know that you can compare apples to apples in this situation, as power delivery has changed a lot since fourth gen AFAIK, you'd need someone who knows CPU architecture and/or more general knowledge on the subject to inform you if this is actually the case though.

Right on.  Well thanks for all the info man.  My EK Kit arrives tomorrow or Thursday, so I'll find out soon enough anyways I suppose!

A five-minute linpack (OCCT) capped out at 92.31w, with an average of 88.81w. (with margin of error for the ~10 seconds at idle before OCCT was initialized and operating)

A run-through of Superposition (1440p, DirextX, fullscreen, extreme shaders, high textures, DoF on, Motion blur off, for what it's worth) produced a max of 265.51w, with an average of 249.83w (with margin of error for the ~10-15 seconds at idle between starting HWiNFO and Superposition loading in and beginning the benchmark)

Again, though, I do not know if this is an apples-apples comparison between generations.
I also can't validate that HWiNFO is entirely accurate.

My temperatures were well within expected range, but are largely useless for comparison as my loop hasn't had time to reach equilibrium and exact ambient temperatures are not recorded (I've come to the realization that I don't own a thermometer other than the one coupled with my HVAC unit, so room ambient is approximate).
(Rough ambient of 13°)

• CPU capped out at 49° (five minute run)
• GPU capped out at 53° (three minute run)

I have a Titan X (980Ti) and 7600K, both overclocked, running on a 240mm radiator with 1500rpm? fans.  The water gets up to about  45-50C under synthetic load (both CPU and GPU maxed out...doesn't really happen in the real world)

 

360mm is fine.
