So my sig has it all but just to recap:

Hardware:

CPU: Intel 2500k @ 4.5GHz 1.35v

GPU: AMD 7970 @ 1200MHz 1.225v

Cooling:

CPU Block/Pump (all in one): Swiftech Apogee II

Radiator: Koolance 2x140mm

Fans: 2xSwiftech Helix 140mm @ 1500RPM

Temps after 30 minutes of Prime95 and Furmark:

CPU: ~80C

GPU: ~65C


Now I know this is running 100% on everything which would never happen in real world use and that my temps are still within safety limits but don't these temps seem a little high?

The radiator is getting fresh air directly from the outside so air flow isn't a problem at all either.

Either way, just curious!

Thanks!

Did you just build the setup with the watercooling gear?
Make sure the CPU is sitting properly and that there are no air bubbles in the system.

What speed are you running your fans at? this was pretty normal for me on an H100i with my fans running at 750rpm push pull while doing Prime 95 Blend.

One of my cores got as hot as 84C in an 18 hour run. But in real life gaming (say like playing Battlefield)... my CPU only gets as hot as 67C-68C at that kinda voltage.

Prime 95 will usually be a lot hotter than what your CPU would run in real life if youre comparing it in the aspect of just gaming...

If your fans are at 1400+ RPM and youre at 80C then there might be something wrong here.... as the temperatures i was getting was based off my fans running on the lowest/most quiet setting possible.

I've had it built for a month or so...everything to my knowledge is properly seated and pasted.

Fans running at 1500RPM. 74.5 CFM. Static pressure 1.58mm H20.

Also, I'm only running dual fans with a CPU AND GPU on the same loop. So according to your temps I might not be doing THAT bad. I mean, my GPU is pumping 200+ watts at 1200MHz...so both on the same loop my temps in comparison seem pretty good.

Again, CPU and GPU on the same loop...so my temps might be normal in this case, no?

Imo you are pushing the radiator pretty hard with both cpu and gpu running. I usually go by 120mm at least per block and then have 120 extra just for when you push the pc. Temps are a little high for those types of fans though but you might be hitting a burn in time for the thermalpaste. I had a time where my temps were hitting ~5c higher but they dropped after a month or so.

OK so it seems I was REALLY pushing my system with the stress testing.

Playing ARMA 3 maxed out my temps are hitting ~50C on the CPU and ~45C on the GPU.

So my cooling is definitely adequate under normal circumstances for sure I would say.

Oh CPU AND GPU on the same loop.... Yeah i would definitely go with an extra 120mm radiator in addition to 120mm per main component. So 360mm total for you. But i see you are using two 140mm radiators.... so i think if anything i think these temperatures are "normal?".

If you had an extra 120mm/140mm headroom you would probably be getting way better temps than my h100i. But since you have both GPU and CPU in the loop; that sounds pretty reasonable that youre getting as hot as 80C (on prime). Have you tried gaming? just watching your max CPU temps? Im sure they wont be as hot?

I dont really get too worried though about being hot on a Prime 95 run. Its essentially stressing out your CPU to the very max capability... and i never really push my CPU that maximum even when im gaming so i dont get too worried if im hitting 84C (as long as its still <90C).

Reasonably; these temperatures are "okay". Would be nice to add an extra 120mm or 140mm radiator in that loop; youll probably be seeing 70's on prime full load.

Unless you sit at home and legitimately "play" Prime 95 or Heaven Benchmark.... your temperatures should be a lot lower "realistically speaking".

That makes complete sense now since the stress tests pushed it farther than any game ever will but I would watch out if you decide to do any [email protected] or anything that would push it close to those temps. Also keep an eye on it during the summer. I have about a 4 or 5 degree difference depending on if its winter or 105F outside since its Texas.

Oh yeah, I did Bitcoin mining once and yeah...yeah...pushed my GPU rather nicely.

Summer time isn't a worry, my house stays ~70F consistently so no problem there.

And just to show it off to everyone, here's my system (top isn't done waiting on custom cut aluminum plate
