A little advice please, hot loop and CPU but cool GPU

the wopster · 17 Jan 2018 at 14:07

I haven’t really taken any notice until I got my 1080ti, but my loop seems to be very hot when gaming, my gpu never gets above 50c even after hours of gaming but my CPU(8700k delidded@5ghz) on the other hand hits 70c when gaming and my loop feels very warm. I’m 100% sure I have all of the air out of my loop and I’m also sure I have enough rad space a 360 and a 240 and my order goes pump/res-CPU-360rad-GPU-240Rad-res not that the order matters and my pump speed is at about 66%. Anyone got any ideas on how to cool it down? I’m thinking of splitting the loop.

That temperature split roughly mirrors my experience once everything is up to temp (although I have 980Ti instead).
As a test, increase radiator fan speed to max and check that all temperatures (CPU/GPU/coolant) drop in unison.

I see similar temps when gaming. My cpu tops out at 63c while my gpu runs 20-25c less.

It seems like you have pushed your cpu hard, what is your vcore for the cpu? Got any wiggle room to drop it? The 8700k run quite warm anyways.

1.35v on the cpu

What temps did you have before adding 1080ti?

the wopster · 17 Jan 2018 at 17:49

Under 60, but the 1080ti doesn’t get above 50c

But did you disassemble cpu block (to clean maybe) when you added new gpu? Is jet plate set up correct way?

Nope just swapped the 1070 to the 1080ti

Well the loop can't be that warm if gpu is at 50C, probably coolant temp is around 10C+ less than that.

My bet would be still on cpu block

even though you've not changed anything.

Which 1080ti? Usually it’s a fan issue not cooling the radiators enough (well enough but not as much as you like). I’m seeing less flow on my GPU block as I had to reverse the in/out for logistical reasons - which orientation are you doing in/out on it/cpu in case you mixed them up?

Its this card and doesn’t have any instructions for in or out, but I have had a look at reviews that have broke the block down and it is the right way

Ah ok so it’s pre-blocked. Do you measure flow? Have you tried running pump at max and seeing if it reduces temperature? So you had the 8700k in (or did not reseat it) and it’s only increased when adding the GPU - but there was an existing GPU in the loop prior to your 1080ti?

Also silly things like is your radiator (Home) on and near the case warming the air through it... Fan speed, is it the same - was it linked to any software? If so potentially you need to update things like AIDA for the 8700k anyway.

Apologies for the spam of questions, just in case you’ve not checked or thought of them and it turns out to be something random.
