yes you are right on this. After 15 days of running, the fan of the CPU has dust and the noise is raised. As a matter of fact i cleaned it yesterday and now i will put in the Sleeve Case of MS-01 a mesh or something inside to the top and bottom of it to hold the dust.One issue with cooling is also dust accumulation, leaving the MS-01 with any kind of load will mean you have to clean it of dust regularly.. That's an issue for a 24/7 server..
I am thinking to take out the sleeve totally and put it inside an HTPC case... after all i have an eGPU to m.2 card on it and i have an Nvidia 1070ti on the machine since yesterday... if i do what i say i will end up with a single box with the MS-01 on it and everything else also with the addition of some normal fans and filters....
Still trying to decide what box to buy.. i have a Silverstone GD10 laying around but i think is too big for what i need.. even though i have it with a LAMPTRON CW611 which is great because it has fan control with temperature etc...
