Help with upgrading Ivy Bridge i5 and Asus P8Z77-V-PRO

[Woody]

Dear Ladies and Gentlemen.
I plan to upgrade my 2012 / 2013 HTPC.
Present HW List:
Case: Streacom F12C
Intel I5 3570K TDP 77Watt (idle 25 - 30)
1 140mm Noctua fan for cpu cooler. Noctua NH L12.
2 x 120 mm Noctua fans for case cooling.
1 GPU: Asus GTX 1050.
16 GB RAM.
PSU: 750 Watt EVGA Supernova G2 in eco mode.
Boots into Windows 7 in about 8 seconds. (bios not timed)
It is 100% silent in idle, (fans spins from 190 to 490 rpm) and you can barely hear it when playing newest version of Doom or Dawn of War 3.
Temperature in living room: 22c.

However, With USB-C, M2 technology, and 2 broken USB connectors on my P8Z77 MB, it's time to upgrade.

I bought the Asus IX Code MB and the I5 6600K and thought this would keep cold and nice.
Excellent board with shitloads of "extra's" and a very good CPU.
Well... After 4 days of temperature troubleshooting, and tweaking, I delivered it back to the supplier...
Reason: Way to hot and noisy to be in a living room. This was clearly nothing for me.
This hardware idle's around 40 for about 15 minutes, then for no reason, sitting on the win7 desktop, you can see the cpu and mb temp steadily rises to above 50 degrees with software.

So now I'm not sure what to do or look for.
I'm not overclocking anything for sure. But still, I want that extra boost when needed.
So how should I choose?
Could the Intel I5 6600 65Watt TDP (without the K) be worth testing?
And what ASUS Motherboard should I choose to make sure the temp's keeps very low.
I am using FanXpert and their AI Suite to keep the PC cold. No other brands are interesting for me.
Also, no mini itx or Micro ATX. Already tested. Way too hot

Any advice?

Did you check CPU usage? There might have been some task(s) running in the background causing the CPU to heat up.
I can't really see how one motherboard would be (significantly) better or worse than another when it comes to CPU temps.

The non-K Core i5 isn't much cooler than the K-version at stock speed. It's overclocking (with overvolting) that turns the heat up.

Proper mounting of the CPU cooler and making sure that the fan is functional should be sufficient.
(Don't know how long (months?) the fan on my Scythe Ninja was broken before i opened the case and found out...)

The other issue with Asus motherboards, particularly performance-oriented models like the Asus IX Code is that they default to Multicore Enhancement being on. In other words given a CPU like the i5 6600k it will turbo all four cores to the maximum 3.9Ghz. Needless to say this will have an impact on cooling.

...and the mobo may have been overvolting your CPU as well...

Wait for coffee lake, it will be released in two weeks, an i5 8600 Will be a very nice upgrade, if you feel it's too much, check the i3 that will be quads.

Well. Thanks to all for replying.
The quest for a total silent and slick looking monster HTPC has been just awesome with Asus MB and GPU, The Ivy Bridge I5, and Noctua fans.
This hardware is more quiet than a mosquito farting.
Mostly thanks to SPCR and some good research.

But from generation skylake and upwards, it seems the HTPC's future is pretty grim...
Overclocking and LED is the shits now.
Just look at this thread @ intel:

So lets see what Coffee Lake brings.

I don't see that. Efficiency is constantly improving, you get more computing done at less power usage.
The future is only "grim" if computing demands increase faster than efficiency.

Overclocking and LED is the shits now.

Sure, but overclocking is still optional (and also allow for underclocking/undervolting) and LEDs can be turned off (as I've done on my new motherboard since you can't see any light through the walls of the P183 anyway...).

But with for example the IX Code, I tried to, in bios, make sure it didn't overclock, and use as little power as possible.
This did not work at all. Same temps no matter. I reseated the CPU cooler twice also.

So with your new hardware, (specs please) what temps do you get after 1 hour of idling?
If any, what settings did you change in bios?

[Olle P]

I'll have to get back about the temps, since I typically don't monitor those. Can't see the relevance of my idle temps compared to a HTPC though...

System specs:
CPU: Ryzen 5 1600. Overclocked to 3.8 GHz with some additional voltage.
CPU cooling: AMD Wraith Spire, stock TIM and settings.
Motherboard: Gigabyte AB350-Gaming-3. LEDs off.
RAM: 2x8 GB Corsair Vengeance 3200, 3066 MHz 16-18-18-18-36, 1,45V.
Graphics card: Gigabyte GeForce GTX 1060 6GB Windforce OC, stock settings.
PSU: Antec CP-850
System drive: Kingston V300 120GB SSD.
Main drive: Some (Toshiba?) 7200rpm 2TB HDD.
Case: Antec P183, with additional pollen filters on the front intakes.
Case fans: Front: Scythe Gentle Typhoon 1900rpm at ~1600 rpm.
Rear: Some Noctua fan at near full speed.
