Suggestions for temperature control.

[266947_1454182200]

I have an i5 7600k with a mild 4.4Ghz oc at 1.35 volts on an Asrock Z270 Killer Mb. Im using an H100i for cooling. My idle temps range from 38 to 45 degrees, usually 40. These higher than what I hav normally seen on reviews and forums with this cooler.

 

Also. When I am playing generally low demand games like Darksiders Ii, Golf With Your Friends, and anything Lego. I will get Temp spike to 90deg then it will level off at around 82deg. I have red that this is still in the safe range for Kaby Lake. 

 

I would point out that my gpu is an Msi R9 390x which i know is a hot card and will reduce cooling efficiency. 

 

So i would like a few ideas on fan/rad placements and fan curves.

How do you have the cooler setup on the top? Are the fans intaking air or exhausting it out of the case?

Idle temps of 38-45C seems a little high, have you tried reapplying the CPU thermal compound to make sure it has an adequate amount?

What is your fan speed set to at idle and then at max load?

Top mounted exhaust. I included a photo. I'll try new thermal compound tonight. I just used what was pre applied on the h100i.

 

[-rascal-]

38°C ~ 45°C is not bad per say.

 

What is your typical ambient (room temperature), and is the CPU set to run 4.4 GHz @ 1.35V constant (even during idle)? All these (including a few other factors) contributes temperatures.

 

What reviews are you using for temperature comparison? Keep in mind, something say...a i5-3570K @ 4.4 GHz may have a different temperature behaviour compared to a i5-4690K, i5-6600K, or i5-7600K running also at 4.4 GHz with the same CPU cooler.

Ok, just for the record pictures don't really tell what orientation the fan is in if it's only a picture of the side lol.

Since it's setup as exhaust you're pulling in air that is already heated up by the 390X. I'd try mounting the H100i at the front of the case as an intake so it's taking in fresh air from outside the case and that should drop your temps some.

The difference between a rad as exhaust or intake won't be much.

 

My bets are on the thermal compound. Air gaps may have formed.

Fans might be slow as well. The fan curves might be too conservative.

Voltage might be a tiny bit high. Try seeing how close you can get to 1.30v while maintaining stability.

 

All these could contribute to higher than expected temps.

I am not sure how overclocking is done these days. Maybe straight inside the BIOS and is it from adjusting the voltage? Reason why I ask is on non-overclocked systems, an easy way to lower temps is to undervolt thw CPU but do it in a variable fashion. Let the hardware determine the necessary voltage needed then offset by a minus value. This normally drop temps significantly in any system. 

 

I would be intereste to know now if you resolve your issue. Maybe with an undervolt using the Intel Extreme Tuning tool

Frankly... there's no easy solution for you. You either mount it on top, sucking hot air from the 390x, or mount it on the front, exausting hot air onto that 390x (and causing it to overheat instead). Either way, one of the components will have to suffer. The best solution would be to sell the 390x and get a more modern, not as power hungry of a card (Gtx 1060 6gb for roughly the same firepower, 1070 if you want a nice upgrade), that would improve temps the most. But outside of it, here are a couple options:

1. You can try lowering your OC a bit, that would help; 1.35v is hot as ballz for a Kaby chip, lower it and your temps should settle down.
2. Instead of top exaust, have it be a top intake. Screw the rad to the frame and then have your fans suck air through.
3. Leave side panel open.

The 390x needs to last for another year. Spent my budget on the new cpu, mb, cooler, and ram. (Just upgraded from an fx 6300!) Lol

Opps, Correction, 4.4Ghz At 1.25v

Replaced Thermal paste. Now Its staying around 35deg Idle and topped out at 78deg.

Thank you and everyone that replied for the help.

Did you try changing where you mounted the AIO? I used to have my Cooler Master Nepton 280L mounted as exhaust in the top of my case with one 140mm fan, the other wouldn't fit due to clearance issues with the motherboard, and when I'd encode videos with Handbrake my hottest core on my 4.3GHz 1.25V 4690K was 84C. I actually just moved it to being an intake on the front with 2 120mm fans and doing the same encoding now my hottest core only gets up to 72C with the same ambient temps. A lot of that is most likely due to the extra fan, even though they're smaller fans, but you should see some more improvement by doing it and it's pretty easy to do lol.

I originally had it on the front but the gpu hit 99deg so I moved it. I knew the cpu could take the higher temps.

 

I Just played about an hour and a half of Shadow of Mordor. The hottest my cpu got was 76 and 80 on the gpu. So the cpu temps have dropped around 10deg on average. I'm not sure if this AS Ceramique  has any cure time or not so it may drop further.

 

I am also thinking about swapping my AF140q intake fans for ML140 fans in the near future.

Yeah Ceramique has about a 25 hour cure time with several thermal cycles to fully cure per Arctic Silver's website so it should only get better lol.

That sucks that your GPU suffered as a result of the positioning. Maybe that's your queue to water cool it too

It would cost me nearly 3 times to water cool the thing than it cost me to buy it in the first place! lol

 

......and yes I looked in to it at EKWBs

 

I figure about this time next year I'll get an RX 590 or Vega(what ever they or going to call it) or a GTX 1170 or pretty much what ever is in the $400 price range at that point. What ever gives me the best bang for the buck.
