Hey guys,

wanting to know if a 420mm rad would be enough for a 5820k and Gtx 1070. The 5820k will be at 1.3v or higher but not yet sure of the gpu.


Thanks.

Usually you can say that 120mm rad space is enough to cool a stock component and 240mm rad for an overclocked one (ofc it depends on the specific component, radiator, fan speed and how much overclock). So two overclocked components would need 480mm radiator. But you can get away with less by amping the fan speed or how much you overclock. So you will most likely be OK. thumb.gif
Hope I helped.

Okay interesting. So you are saying then that a 360 rad plus a 120 would be a better option. Hhmmmmm.

One thing I forgot to mention is that I live in the Caribbean.

The H110i GT kept the 5820k overclocked at low 70s with phanteks fans running at about 80%, so using that assesment I assumed that a 140mm additional for a graphics card is more than enough as most of the time a 120 does a good job. The fans will either be EK's F3s or Corsair ML 140 pro series.

A 420mm radiator would be plenty for your setup. Your fan choice and the RPM you will run them at will play a big role. Which fans are you using?

That rad setup might be better but remember 2 individual rads will cost more and require more fittings, tubing and fans. Also The thickness of the rads make a difference.
Here you can see that EKWB has three different thickness versions for the 120mm radiators.

Not sure which rad I will be using though, just something I don't have to run fans at full speed. Any suggestions?

Hence why I was looking at the 420 rad.

Thickness would be dependent on case. But 30mm if I choose Inwin 303 or 45mm if I choose another case.

Right now i'm running a 4690K @ 4.5Ghz and 1070 @ 2050 with a single XSPC 360mm Crossflow radiator fans at 1000RPM.
CPU Temps: 45 - 50ºC gaming - 65 / 70ºC AVX
GPU Temps: 42ºC
Adding the GPU to my loop only increased the CPU temps 5º degrees

It's all mechanical, you can mend it with a hammer !

I have used Hardware Labs, Alphacool, and XSPC radiators over the years. Hardware labs has the cleanest and most well built of the bunch in my opinion. Performance has always been great thumb.gif

There stealth/slim lineup would be my recommendation based on those cases you listed.

Okay, thanks.

What is the difference between the 'L' line and 'GTX' apart from the price and width?
