Intel I7-7700K Undervolting Help

[TheMilitantGamer]

Hello all! New to the site, and not sure if something like this exist. If so, point me in the right direct. 

 

So yesterday I got a new gaming computer for an early Christmas gift. Normally, I'd build my own, but why look a gift horse in the mouth. Anyway, I set it up and noticed that Out of the box stock, this Liquid cooled 17-7700K is running at 38 Degrees C, or 100 Degree F just running Win10. I updated the drivers, the OS, removed any bloatware, did a clean reboot, and nothing helps. Even other things seems to be running a tad high. The M.2 SSD is showing 39 Degrees C (102 F) om CPUID, and the GPU is also running hot at 37 Degrees C (98 F). So my first idea was perhaps the 850 Watt PSU is delivering more power to the mobo than it should. But the only idea I have is to under-volt the cpu for the meantime while I await an order of better thermal paste or something. So I pose two questions:

1. What is the best setting in the Intel Extreme Tuning Utility for an 17-7700K? Or what can I change in the Bios of an MSI Z270-A Pro to get CPU temps down to say 60 F or lower. 

 

2. Is my idea on the PSU being too powerful correct, and if not, what could be the issue to cause all major components to overheat. 

 

This is a pretty bad issue. After 90 minutes of PUBG, the CPU read a major 173 Degrees F! And as I said, idle is 100 Degrees F. Fans are blowing air in and out, and the cables are professional managed, And since its new, dust isnt an issue. Also, CPU issue is not an issue, as on idle CPU useage is only between 3-7%.

Anything under 90 C under load is fine. /thread

That sounds fine to me. Did you OC it? If yes, what's the clock speed? Also, what cooler are you using? (If possible please provide the full specs)

This will NEVER happen

Why buy an unlocked CPU and undervolt it? You should OC it to gain performance

[TheMilitantGamer]

Well it hits 90 C and goes higher when gaming, the purpose of this computer. It hovers sometimes at 87-89 C in Warframe, and hit 90 C easily in PUBG.

[TheMilitantGamer]

ZM Fong: Im not sure. 173 F is 87 C. And I would OC if the temp wasnt so high. And no, I didnt OC it. I mean, every fan is blowing alarming hot air out of every fan.

TJmax <100C
TCase <72.2C under load is fine.

 

Signed, Intel setting their Parameters, not some random internet Joe.

 

@TheMilitantGamer Reseat the cooler, make sure it's firm (or use the o-ring method on the bracket) and tightened by cycling screws (otherwise it's not tightened down straight). Turn off things resembling "all-core turbo/enhanced turbo" etc.

[TheMilitantGamer]

Huh, well under load perhaps. 100 F at idle? Just running Win10? Is that normal? My old FX-8300 build never got that high even under load. And where can I find this Turbo setting to disable?

But is it actually idling? Have you verified the load is 1-2% max? Have you verified it's actually clocking down, and lowering the voltage (CPU-Z)?

[Las_Killar]

What cooler are you using?

[TheMilitantGamer]

Majestic: With nothing running but Win10, the lowest I have seen is 3%, with the CPU clocking down with most cores between 0-1% activity. I am guessing something on the OS is still running, but I disabled all unneeded services and still this happens. And you still havent told me where the turbo setting are to disable. 

 

Las_Killar: Unsure. I know the brand is NZXT and the top of the contact plate has a G symbol with a lightening bolt?

Okay, can you see if the radiator is equipped with one or two fans?
Cause it might be the cooler is to small, but that would only be the cause if it was the 140mm radiator (one fan'ed rad)

[TheMilitantGamer]

It has a radiator with two fans on the fore and aft of it. The interior fan has a red light surrounding the perimeter of the fan, and the blade seem to be made out of some rubber type plastic. The fans are 120MM.

They're irrelevant is Idle is high. To be honest these issues are only really solvable if they're genuinly extreme, like 100C in a few seconds. Then you can diagnose the pump isn't running etc.

 

But this, you're probably doing something wrong with mounting the thing and noone can verify if you did a good job.

Okay it sounds like you got the NZXT Kraken X52 and that should be more than enough.

 

I would then try and go with Majestics advise, and reseat the cooler on the cpu

Majestic: Actually, I've been building PC's for a while (Not saying im the bees knees, but I built my last two computers and they lasted years with no issues). And I stated that this was purchased for me, which means I did not build it. I checked the cooler when I got it and it seemed to be alright, however I do plan on replacing the stock thermal paste with something much better in the next week. The reason this concerns me is I have never, ever seen a processor be deemed "normal" when idling at 100 Degrees F, but I have never had an Intel processor since Pentium 4 was a thing. 

 

Las_Killar: Right On. I think I still have some Arctic Silver 5 somewhere, but will have to go though my computer tool kit. If not, I have some being delivered.

Depends, is the ambient high (IE what is the Tdelta)? Are you checking idles on a waterloop mere minutes after taxing the system (meaning the water is still warm)?. This kind of loops back into the notion that other than telling you to change out the TIM and reseat the cooler, we can't do much.
