Linux за българи: Форуми

Здравейте можете ли да ми кажете програма или нещо подобно което да намели скоростта на вентилаторите на моя компютър dell studio 1535 защото постоянно работят на максимум и вдигат страшно много шум. докато преди на убунтуто се включваха за малко и после пак ставаха тихи.
Благодаря предварително.

свали и инсталирай htop
(yum install htop)
и ни кажи коя програма заема най-много от процесорното време.

ами най много процесорно време харчи гнома.

И други имат твоя проблем. Трябва да си обновиш биоса. Намерих го, като потърсих в google: "dell studio 1535 fans"

http://shield008.blogspot.com/2008/12/dell-studio-1535-fan-seed-problem-and.html

Добре това го направих всичко update-нах биоса, но проблема с вентилаторите остава все още са по шумни от колкото с ubuntu.
Резултатите на lm sensor-a са 50градуса а едното ядро и 51 на другото. Което според мен е добре. Но вентилаторите въртят доста повече от преди.

какво да ти река, виж ако на живо цд на убунту е ок. Какви модули, демони и процеси ти е заредило и виж дали може да направиш същата дандания на федорката.

Настройките на cpuspeed? fancontrol? Там всичко ли е наред?

не знам дали ти трябва това, но нека предположим.
Това е за cpuspeed
