high temps after overclock advice needed

dane3206 · 21 Aug 2018 at 13:55

Hi guys,

looking for some advice.... purchased the deal overclockers had on (i7 8086k, Asus maximus x hero, teamgroup 16gb 4000mhz ram kit, and the asatek 240mm AIO) This has been paired up with the NZXT h700 case and a gtx180ti ftw3.

CPU core speed is at 4900mhz 1.3v

Ram 3400mhz at 1.35v

Cooling set up is ….. 3 case fans at the front of case pulling air in normal rear fan working as an exhaust and AIO fans pushing air from case through radiator out as an exhaust. All fans are set to maximum speed manually in bios.

Just been running realbench stress test for 15 mins and CPU temps hit a max of 93 degrees where have I gone wrong? is the cooler not up to scratch? was only built 2 weeks ago so thermal paste new (thermal grizzly) Any advice would be appreciated.

you can try to adjust the following voltages to help reducing the temp:
1.Load line calibration level 6
2.Manual voltage 1.3v (should range from 1.296v-1.328v in cpuz)
3. VCCIO 1.05v
4. VSA 1.05v

still at 1.296v (wouldn't increasing the voltage make this worse?) with VCCIO at your recommended voltage hit 90 deg within 3 minutes so cancelled this test I already had your other suggestions set on the bios any other ideas?

What BTVA said. Automatic voltage setting is probably way to high.

But keep in mind your 240mm CLC is not any better, maybe not as good as a good air cooler .. and most likely making more noise too.

try manual 1.25v instead and if the temp still high, you should try to re-seat the cooler.

helps a small amount still at 86 degrees ill take it off and try re seating it. What if it doesn't make a difference new cooler?

BTVA · 21 Aug 2018 at 14:59

one more thing you could try is using the AVX offset option, set it to anything within this range 2-5 could also help.

and this as well

dane3206 · 21 Aug 2018 at 15:25

set to 3 made no difference

and haha It came pre pasted and I cleaned it off so I deffo know it cant be that.

BTVA · 21 Aug 2018 at 15:37

Hmm if I’m not mistaken the asetek 240 has similar performance compared to Corsair/NZXT same size coolers so it should not be too bad.
Apart from all the suggestions, you could try to delid it, but it would void your warranty tho. Also try a different cooler might help, I recommend good air cooler instead of CLCs.

dane3206 · 21 Aug 2018 at 15:41

I thought they was supposed to be decent but obviously not. thanks for your advice i'll try and reseat again and re paste. If same happens I will look into a new cooler I only use it for gaming and I'm not getting anywhere near them temps so should be good for now.

What are the case intake fans? How hot is the air in the case, since this is what's going to be blowing through the radiator?

dane3206 · 21 Aug 2018 at 22:09

There just the standard x3 120mm which comes with the nzxt h700 case. Don't have a temp probe or anything in the case but the motherboard temp stays nice and cool I can game for hours on intensive games at 1080p ultra and do well to ever hit 70 degrees. Took the cooler off and 're applied thermal paste earlier still hit 85 in real bench

Unseul · 21 Aug 2018 at 22:23

So the intake fans will be fighting the restricted front, and the dust mesh?

I see there's a special case version of the fans, I wonder what the difference is. Most case fans are seemingly quite poor though. I saw about a 10c drop in my case temps (x370 board came with thermal sensors so I have one just sitting at the bottom of the case) when I went from the 2 120mm fans supplied that didn't have the strength to pull through the mesh, to 2 good 140mm fans. That dropped my temps for components by about 4c when under load.

Your fans are better rated than mine were, so might be able to supply some actual airflow (assuming the case version isn't worse than the regular one).

Looks like it wasn't the paste

. If the calculation is right, it seems you're just right up against the limit of the cooler.

dane3206 · 21 Aug 2018 at 22:28

Do you mean the h700i? If so think it's just comes with the cam software which isn't rated highly I usually pull the front cover off to aid cooling with the dust cover makes a little difference but nothing substantial. I agree mate for gaming temps fine so I'll invest into a better cooler soon.

Unseul · 21 Aug 2018 at 23:23

The case fans that come with your case are specifically labeled as case version, rather than what you'd buy separately. I don't know if that's a good thing or a bad thing, couldn't find any review that compared the two.

Try a desk fan blowing into the open side and see if that gets it back down. Might be if your case air flow isn't good enough that you need new intake fans, which will prevent hot air getting recycled and pushing your cpu temps up.

Doyll recommended the phanteks 140mm to me ph f140mp i think is the name. Very good pressure ratings at very reasonable sound levels. Very pleased i took his advice on them. The pressure rating is what they need to overcome obstructions. A low pressure rating could have enormous cfm numbers but not actually achieve anything if trying to get air through a filter. Whereas something with a good pressure rating will be able to suck air through.

Now looking at getting a proper tower cooler myself instead of the stock fan.

Couple of good intakes can move with your builds as you go, just like a good air cooler.

You may be best asking here. https://forums.overclockers.co.uk/threads/8pack-red-friday-bundle-support-thread.18826880/

8 Pack is keeping an eye on the thread so should be able to help you.

What Unseul has said.

We need to rule out the possiblity that airflow inside of case is pre-heating the air going through radiator.

9 out of 10 240mm CLCs are Asetek made and same CLC with different fans and minor cosmetic differences and labels.

A good air cooler with a couple good case fans will perform as well and be quieter too.

You have a real grudge against AIOs lol

Swap the exhaust fans on the radiator to intake and your temps will drop. Get fresh air through the rad then worry about getting that air out of the case

So the CPU will be cooler, but everything else, including the VRMs that'll be working hard with the overclock, will be cooking...

He's close to thermal throttling on the CPU anyway.

He has 3 intakes on the front pulling in air, I can't see how his air temps would be bad enough in the case for VRMs and other components to start overheating, I only have 2 intake on the front and they go through my AIO, 1 exhaust on rear and 1 exhaust on top. He has much better cooling than I do and his temps are terrible.
