Hello everyone,
I have this machine, to cool it well, I installed a dynatron K129 and a noctua A9x14, 27 of height for the dynatron and 14mm for the noctua for a total of 41mm all internally. I added an external 90mm bequiet ....

I think, except the power of the power, you can fit a cpu "K"labeled, and cool it properly with double fans ......

I wasn't sure but I suspected as much too. Given the site has recently been overhauled (it looks and works great now) it must have somehow slipped in there by mistake with all the other work going on.

The i5-7600K is also included as a compatible CPU.

Did Asrock make a mistake?

Yes, I am sure that is a mistake. There is no reason any processor with a TDP greater than 65W should be included in the CPU Support List of the DeskMini, of the H110M-STX mother board.

[QUOTE=qeshi]Hi!

I have several stock Intel 115x CPU coolers provided with other Intel K processors, and used one of them with my DeskMini 110W initially. I was not happy with its performance, although it was not inadequate for the job. I'm just fixated on low CPU temperatures. I bought a Thermaltake Slim X3 CPU Cooler, which fits in the mini-STX board fine. I was even able to replace its 80mm x 15mm fan with an 80mm x 25mm fan, which fit in the DeskMini case fine. The maximum height of the CPU cooler is 42mm IIRC. But the width of the CPU cooler is also restricted, so you must be careful not to ignore the width. The Thermaltake Slim X3 CPU Cooler's dimensions are 99mm x 91mm x 36mm (stock fan.) Other options for CPU coolers are the Cryorig C7, and other small CPU coolers.



I will try to fit a SilverStone Argon AR05 in my build :

Its size is : 36,7 x 104 x 92 mm

I hope it will fit.

The other models of ventirad you mentioned are not very well distributed in Europe.

I will stick with a non K version probably with the i7 6700.

The CPU coolers you gave doesn't seemed easily available in Europe but I will keep looking (if it worth changing Intel stock one)

Excited to build this thing :)


I think it is worth changing from the Intel stock fan. Intel does not include a stock CPU cooler with the 'K' processors.

What CPU cooler brands are available to you?

The small Noctua coolers like the NH-L9i will work with this board. You must be very careful that the CPU cooler is no more than 95mm x 95mm wide, and not more than 55mm high, including its fan. Otherwise the CPU cooler will not fit in the board, or the mother board tray will not fit in the case if the CPU cooler is too high. You cannot take the top off of the case, it is one piece.

 The ThermalTake Slim x3 I use is 92mm x 99mm, but it will fit if it is mounted so the longer side is turned away from the heat sink for the voltage regulators. It also depends on the mounting system of the CPU cooler if it will fit if it is a little larger than 95mm x 95mm. Don't just buy one that you think will fit, you really must be sure it will fit.

Hi,

So did you build the PC ? Is it working well ?

What about putting an i5 6600K ?

I am also looking for references to replace the stock intel ventirad by a more efficient solution.

Thanks for your help


My DesiMini 110W works great, no problems with it at all. I use an i3-6100 CPU with it. I have an Intel 600p M.2 SSD as the OS drive with Windows 10, and a Samsung 840 Pro as a data drive.

An i5-6600K will work in the H110M-STX board, but its TDP is well beyond the specifications of the board, which is a maximum of 65W TDP. The i5-6600K has a TDP spec of 91W.

It is not only the cooling capability of the CPU that matters, but the power it will use. A CPU with a TDP greater than 65W will also use more power. The power supply of the DeskMini 110 is rated at 120W. It is a good sized PSU, but is not designed to provide limitless power to the board.

Also, the power supply provides 19V DC to the board, similar to a laptop PC. The voltage regulators to change that to the standard +12V, +5V, and +3.3V used by PC components are on the H110M-STX board itself.

This voltage regulator stage is well made, but is not designed or meant to supply the higher current used by processors with a TDP greater than 65W. Using a processor like an i5-6600K at it's full speed with high CPU usage will load the voltage regulators beyond their intended output. That will cause them to over heat, shut off to protect it from damage, or even damage them permanently.

The UEFI/BIOS does not have options to reduce the CPU multipliers or BCLK frequency, to under clock high TDP processors. This PC and the Mini STX boards are simply not designed to use any of the 'K' type processors. I cannot recommend using any Skylake 'K' processor in the DeskMini PC, or any of the H110M STX boards that use the 19V power supply.

For cooling a processor with this board, one replacement for the stock Intel cooler is the Cryorig C7. Another option is the Thermaltake Slim X3.
