I ask for your opinion for cooling an i3-4130T (tdp 35W) only with this cooler (tdp max 95W) or with the Thermalright AXP-100 but, for both, w/o their fan, in order to get a fanless system. The case is M350 or very similar.
The work will be office, internet, sometimes video full hd, nothing of heavy...
It's possibile this operation?
A passive cooler needs some sort of airflow.
Noise will come from a fan running at high(>900)rpm.
The stock Intel cooler should be fine. Under normal or light operations, the pwm fan will run at very low speeds.
I have build 3 desktop/internet systems using the fanless lian li Q07 case and the stock Intel cooler. Noise is never an issue. With a low power chip, it should be even more quiet.
I would try the stock cooler first.
Any noise you get is likely to come from your psu.
If you use the Gabriel cooler, undervolt the fan so it runs at 600rpm and you will never hear it.
Where will the 35w heat go?
Natural convection may not be sufficient, depending on the case.
If your psy has a fan, that might be sufficient.
But a psu fan is likely to be noisier than a 120mm fan on a cooler.
If the cooler fan is a pwm controlled unit which is normal, you can use a program like speedfan to increase the speed if the cpu temperature gets too high.
IN the end, what is your objective?
If you want quiet operation, that is easy.
If you want silent, that is possible.

Go ahead and try it both ways and see which you prefer.
I am not familiar with the case you are using. But as stated, you need to ensure there is sufficient airflow in order to keep things cool enough.
What you plan on doing is possible because I have a passively cooled HTPC that is built around a Core 2 Duo E6600 with a Tuniq Tower cooler (775 grams I think with no attached fan), and a passively cooled nVidia 9600 GT with 5 hard drives.
Actually the fan is attached, just not plugged in. Should my primary rig goes out of commission for whatever reason, I can easily plug in the fan an use it as a backup gaming rig which is basically what it was before I put it into a HTPC case. I think the case is a Silverstone Crown CW02.
The only component with a fan is the Seasonic S12 500w PSU.
