Uhm, might be the case :-). It happens tht I never used eclipse in suse, and
maybe because of that the PC never got really hot. My brother has just tried
using it in SuSE and you know what ? CPU throttling turned to 75% also when
fan started to spin! And as in Ubuntu, echo 0

Yeah, that seems reasonable to me, also. But it seems that it's not exactly
the case: it seems that my CPU go slower
when /proc/acpi/thermal_zone/THM/temperature goes to ~65 ºC or so, which
doesn't seems very high (for example it's now working at 52ºC) to me. As a
matter of fact, see:
critical (S5): 100 C
Ah, but the funny part is that when fan start spinning, temperature starts to
decrease and decrease: normally up to 41ºC. But even when running at 41ºC,
the fan continue spinning and throttling doesn't want to move from T7/75%. ¿?

You helped a lot ! it just happens that something that might be obvious for
you it could be not so obvious to me, and thus dialog is the key to solve any
Have a nice day,
