Radiator question

[fantasticCG]

would a 360mm radiator be enough to cool a 9900k and a RTX2080?

Thanks

Stock? Yes. OC? You're pushing it, depends how loud you want the fans to run and what the load on the system is.

So a 420 would be better or 2 360s instead? There would be an OC.

Thanks :?

I am running a 7800x at 4.5ghz and a gtx 1080 overclocked with a 360 rad with no problems...top temps during gaming is 40c on gpu and 44c cpu...hope this helps

I'd recommend a little more radiator space. The 9900k is a hot chip and the 2080 will also generate a lot of heat. I'd suggest a 240 per device, so a 360 and some additional space somewhere.

How fast are your fans running? I have a 1070 and 4690k with 360 and 120mm rads, temperatures peak at 53-55. But then I'm aiming for silence.

I’m running an 8700K at 4.7Ghz (this will go up!) and a gtx1080 at about 2200Mhz, with 360mm and 240mm (GTS 30mm) rads. Temperatures are excellent.

I think you might be ok to OC with a 360, but you’ll be limited, the fans will be noisy and I personally wouldn’t.

I’d say your best bet is a minimum of a 360 and 240, especially if you want the system to be quiet.

Your temps are fantastic on a 360. I’ve got an 8700k and the same GPU. Are the fans loud? Only noise in mine is that bloody DDC, can’t wait to swap it out.

What does your GPU boost to?

 

[fantasticCG]

Thanks guys for the replies, fans I might be going for those thermalake ring trio fans 120mm if I I get a 360 or the 140mm for the 420.

I’m still working it out wanted to build in the Phanteks evolve X case, so just weighting up options and trying to plan the loop.

Better going dual loop if you can, keep them separate. Could always AIO the cpu and custom loop the gpu, some nice integrated pump/res available these days for custom loop.

I've gone from 4x480 monster case with sli down to single gpu hybrid (120mm) and cpu aio (360mm). Temps totally fine on both.

 

[Griff7520]

gpu runs at about 2100 as its set in afterburner with a couple of hundred extra on the memory, my pump is set at a constant 3900 rpm as I found this to be able to keep the temps around the same...I tried a slower and a faster pump rpm and my settings seems best. fans on rad arn't to loud to be honest but run about 1200 idle and ramp up to 1500 during gaming and go full when benchmarking with something like occt. fans are no problem for me anyway as I have headphones when gaming so can not hear them....pump seeks almost silent, very hard to hear it.

Interesting any recommendations on the pump/res combo?

 

[Doug2507]

EK are usually my go-to for custom loop stuff. Even managed to dual loop a carbide 600c with a pair of the 120 pump/res combis. Sometimes use alphacool but can't stand the crappy branding on them, no class.

Google best bet as once you've decided on pump it's all down to personal taste for looks.

I like pwm DDC for single rad or d5 vario if it's a bigger loop.

If space is tight you've also got the QDC ek stuff with pumps built into the rads but the hoses are quite thick.

Quite liking the look of the 360mm acrylic flat res right now also but that's taking up a rad slot. Can't remember who's making it...?

More surface area would be better if you can fit it in.

I think my setup is comparable to yours. 9900k and 1080ti.



Running a 40mm 360 with 1080ti and 9900k the loop idles in the 30s.
At load the fans ramp up but this is not a problem since they only do that when gaming and I wear headphones.

But, that seems to be with decent silicon and low ambient temps. The fans aren't sucking summer air through the rad right now and I'm able to use a low voltage on the CPU so it isn't chucking out loads of heat.

Upping the OC on the 9900k pushes temps up and so does using a different hotter running 9900k (even at a lower oc).

Right now my GPU isn't OC at all.



As i said above, you could use a 360 but I think you are pushing the limits of how much heat it can dissipate with an overclocked 9900k and 2080.

I'm adding more radiator space to my loop to give me more OC headroom. It should also mean the fans come on less and things remain cooler for longer when warmer weather arrives.

120x120 for each component +1 for safety. I think a 360mm would be fine unless you're planning on running full load for extremely sustained periods (i.e. distributed computing/mining)

If it's just for gaming, get really powerful fans and a fan controller so you can ramp up when gaming. Much cheaper than running multiple rads and/or dual loops.

 

[WantoN]

I don’t see any benefit to dual loops unless your setup is HUGE. Just more cost and more epeen status.

A decent pump will run a large loop no probs. You could run two in series if you want, whicheould add the benefit of redundancy.

 

[fantasticCG]

To cool a 9900k and 2080ti I’ve gone for the black ice nemesis 360GTS and the 240GTS
will be using a D5 pump.

Another vote for two seperate loops here. I have never fancied pumping water that would still be warm from a block into another block.

except it really doesn't work like that. The water flow thru blocks means the water actually picks up very little heat for each molecule. it's the quantity of water that cools the block. so the overall loop's cooling versus heat sources is all that matters. The water temperature equalises. It has been shown that having pump-block-rad-block-rad-pump makes no difference over pump-block-block-rad-rad-pump.

So all you have to worry about is a) does the cooling capacity exceed or equal the heat sources and b) can my pump maintain flow for the given loop's resistance.

Your loop should be ordered to minimise resistance only. As few bends/fittings and as little length as possible.

Interesting. What's your source for that?

This is well documented. Loop order makes no difference (providing it's flowing in the correct direction of course). Temp equalises.
