So my sister brought my newphew a pre built system from OC 18 months ago its an i7700k, Asus Z170 Pro Gaming, 1070FE and Team Group 3000MHz. It come in a basic case with half decent cooler which I have since swapped for a Phanteks P400s and my old Corsair H110iGT.

Now its always been hot and hitting high 80s in games which sends the fans into overdrive which my newphew moans about but their house is a furnace so its tough to get under control. Running stress test will cause it to hit 90s very quick and shut the tests down.

I thought about delidding which will help massively but one its still under warranty plus its not mine so its not worth the £300 risk to me. Currently I have disabled boost so it only hits 4.2 at 1.2v which sees temps hit low 70s during stress tests in a hot room. The fans only just start to ramp up at 70 so all I can hear is the pump.

Is there anything else I could try or just leave it with the boost disabled as that does solve the high temps but at the expense of 300Hz.
 
A) Does your nephew need the 300MHz on one or two cores as it would typically reach?

B) have you checked airflow, dust in cooler etc? 80s seems hot for any AIO cooler.

Nah he wouldn’t notice at all to be honest. It does need a clean which I’ll do tomorrow.

It’s been running real bench stress test for 30mins with 1 core hitting 81 and others at 76-77. The room is probably 28-30 so hot as hell.

I think peaking at 80 in the hottest part of the year is probably pretty ok. Seems like it could be better but nothing to worry about!

Yeah happy to keep it under 80 during real bench stress test actual was around 75-76. If it was mine I would be delidding it and overclocking but just not work the hassle with it not being mine.

Might look t replacing the 110iGt at some point as the pump is annoying which is why I replaced it with a D15 in mine.

Running 76-77c with one core hittig 81c in 28-30c room is not bad at all. That is about 68-73c in normal temp room.

There is a good chance with a little work on case airflow (maybe a new fan or two) we can get the temps down 4-5c. What exactly is this system; what case, mobo, RAM, cooler, GPU case fan placement, etc?

When was the last time it was thoroughly cleaned? As in not just the case intake vent filters but cleaning the fan blades, cooler fins, etc.

Cleaned it this morning and the dust wasn’t too bad, ran test again and got pretty much the same results 75/76 ish. Again room was noticeably hot.

It’s has H110igt as front intake as it can’t be mounted anywhere else and 1 exhaust at the back. I’m happy with the temps now but just wish it was with the boost enabled to get the full 4.5 out of it.

Well, H100i GT isn't a great cooler that only scores good temps by being extremely loud .. and it's heating GPU airflow meaning GPU is running on even hotter air then the room is. :p

These CLCs are known to start loosing cooling ability after year or so of heavy use (like you have there in hot room) and often fail after a couple years. I've had a air few serious overclocker's tell me they were replacing their CLCs every 1-2 years before coming back to air or paying the high price of custom loop (because they were fed up with CLC problems and noise).
 
Yeah it’s not great, can hear the pump no matter what and the fans are audible over 1000rpm and they get upto 1900rmp when the temps start to rise which is why I went for Noctua D15 in my new build.

Guess I’ll just leave it with boost off as it seems to help a lot. It’s only hitting mid 70s in this heat so will be good when it cools a little. I think next year I’ll look to change the cooler and delid.

The 1070 does run hot which is fine as it’s during gaming when the fans kick in so it not as noticeable. I wouldn’t have gone for a founders edition but it was a pre built system.
 
Your temps sound fine, considering room temperature.
If it's CPU fan/pump noise that's bothering you then I'd be looking at a different cpu cooler.

They are fine now I have disabled boost as the vcore is only at 1.2. Boost was taking it to 1.3 and the lowest I could get it down to was 1.24ish which still resulted in high temps.

Since it’s not mine I’m reluctant to spend money just to make it quieter for him and disabled boost seems to sort it out so I’ll just leave it like that for now. He won’t even know the difference so seems a a decent trade off.
 
just remember that your temps are still within acceptable operating temperatures. cooling it down by 5-10c will do nothing for performance on the CPU. The air that comes out the back of the rad won't be that bad and only going to raise the GPU temp by a couple of degrees.

also given the front of the case is crap for airflow consider putting the AIO at the top as an exhaust (take the front off and see what happens to the temps) with the rear fan set to intake to blow cool air in at the top which will help with VRM temps as well. you have an FE card which blowing air out the back so shouldn't affect in case temps too much and without a AIO at the front you can place a fan to blow cool air towards the GPU.
 
None of the P400 modlessupport top radiators.

I agree, taking the front off will greatly improve airflow, but not sure if it will lower noise much.

I designed some front mounting pin extensions to move front panel out so there is an additional vent gap about 5mm wide all the way around the front. Problem is I don't have access to 3D printer or software to layout and print them.

Might be worth dropping the voltage and see if it's stable. I'm at 4.5Ghz and need about 1.160v so you might be able to go lower and save some temps
