Although the case capacity is very small at 8 liters, it is a dream PC case that can also accommodate a graphics card.
However, there is a problem that comes to mind when a PC case becomes small, isn't there?
That's right.
This is a problem.
Of course the stock cooler “Intel Laminar RM1” on without “K” CPUs such as 12400/13400, 12700/13700 is fine, but there is still a difference in performance.
The following graph compares 1. Intel Laminar RM1 and 2. Noctua NH-L9i-17xx.
Noctua's fans are thinner, but perhaps coupled with the performance of the studied heatsinks
What is even more astonishing is the low noise level.
There is a difference of 5 dBA, quite a difference in physical sensation. While the stock fans are considerably louder.
I think the laminar is also affected by the fact that the fan rotation speed changes at a dizzying pace.
Using a genuine Intel cooler is good, but in this case, something with a little better performance is recommended.

Further improve Noctua NH-L9i-17xx
In fact, the noctua NH-L9i-17xx has a surprise specification: the fans can be replaced.
I exaggerated… but it is not a backstage trick or anything, and long screws for replacement are properly included.
The default fan is the NF-A9x14 HS-PWM, a thin fan with a thickness of 14 mm.
This can be replaced with the NF-A9 PWM. The thickness is 25mm, which is the thickness of a normal, common fan.
上からみてもわからない 左 14mm 右 25mm 25mmに交換するとlaminarと同程度の高さ
What a subtle result….
As for the 12mm and 25mm thick fans, they do not seem to make much of a difference.
At first glance, the 12mm fan appears to be superior (especially right at the start = the part where the 12700 is running at 125W).
The fan speed was also much higher, so it appears to be cooling better than the 25mm fan.
In my opinion, the heat dissipation performance of the heat sink itself may be the limitation rather than the performance of the fan.
As for quietness, the 25mm fan is numerically quieter than the 12mm fan by 1 dBA, but the 25mm fan is quieter by feel.
It's kind of…roomier than the 12mm fan.
In contrast, the laminar sounds like it has no room to spare.
By the way, if you replace the fan with a 25mm thick fan, it will be this close to the power supply.
Conclusion
The 12700 class can be used with Desk Meet B660
However, choose a CPU cooler
Stock CPU coolers should be avoided if possible.
Switching to noctua H-L9i-17xx class will give you mental peace of mind, quiet and a few degrees lower temperature.
You may replace it with a 25mm thick fan, but it will not make much difference at 12700.
(Prediction) In the 12400 class, there is more room in the heat sink in terms of thermal capacity, so the 25mm thick fan may be more effective.
