[Risolto] Ventola impazzisce e Temperatura CPU anomala

[JHKevlera]

Purtroppo da quando ho installato Ubuntu 14.04 sul mio asus vivobook s200e, ad alcuni riavvi (non tutti) la ventola impazzisce e gira alla massima potenza, producendo un rumore allarmante visto che non si è MAI verificato in due anni di utilizzo di questo notebook con Windows 8.1.
Googlando ho trovato problemi simili in condizioni diverse (spesso alla sospensione) e soprattutto su pc diversi. A qualcuno è successa la stessa cosa e sa come risolvere il problema?
Immagino che anche nel mio caso sia un problema di CPU o scheda video che si surriscaldano (o i sensori impazziscono), quindi ho installato lm-sensors, che mi da la temperatura dei due Core che oscillano intorno ai 60°C. a riposo e 77 sotto sforzo (film HD). Nella configurazione iniziale ho sempre accettato gli scans fino a quando non mi ha detto che il successivo scan, non troppo raramente, mi faceva esplodere il pc (parafrasando), quindi mi sono fermato. Ecco i risultati:

E' troppo? Ho installato indicator-cpufreq e impostato su risparmio energetico e laptop-mode-tools. Da terminale ho modificato il file di configurazione in questo modo:

Codice: Seleziona tutto

sudo gedit /etc/laptop-mode/conf.d/cpufreq.conf

e ho impostato questi valori:

BATT_CPU_MAXFREQ=slowest
BATT_CPU_MINFREQ=slowest
BATT_CPU_GOVERNOR=powersave

Seguendo questa guida: http://italiaunix.com/index.html/_/soft ... eria-linux

Lo scopo iniziale era aumentare la durata della batteria (purtroppo ridicola, intorno alle 2h), ma senza risultati evidenti.

Avendo readahead-fedora non ho avuto bisogno di programmi come prelink o preload (e di fatto non ho notato significative differenze in termini di prestazioni). Ma tralasciando il problema della durata della batteria, come risolvo il problema della temperatura anomala della CPU e della ventola che impazzisce e mi fa saltare il cuore ogni volta?
Help please

Manda il risultato di top, inoltre che driver hai?

e il resto non credo importi.

Comunque sotto sforzo (film in HD con cavo HDMI) il processore era intorno ai 70°C..

[JHKevlera]

Ho fatto parecchi riavvi e il problema non si è più presentato.. Immagino il problema fosse della cpu, risolto con laptop-mode-tools (?). Rimane il problema della temperatura della cpu che a 'riposo' è intorno ai 58°C e sotto sforzo sui 72°C. E' normale avere una temperatura del genere? O urge qualche modifica per abbassarla?

Pochi giorni fa stavo provando le stesse cose su un laptop : Acer Aspire V5 ( modello 121 ) , 4 GB di RAM, schermo 11,6 pollici ,

noel@pc:~$ 

.. c'era una differenza tra quando provavo ubuntu 14.04 da live , a quando poi la installavo .
La prima cosa che facevo era installare lm-sensors , però avevo detto YES a tutte le domande , e mi ero trovato con il pc fisso dai 75 ai 85 gradi .
Ora ho installato i driver video dal sito , non ho rimesso lm-sensors , nè indicator-cpufreq , e le ventole e tutto girano molto meglio ... non sò se appunto possa essere lm-sensors che carica la cpu... ora qui le ventole non partono più come prima ....

[JHKevlera]

A me è successo il contrario. Le ventole partivano in qualche riavvio e cercando di diagnosticare il problema ho installato dopo lm-sensors (che credo legga soltanto i sensori dell'hardware e comunichi la temperatura, non credo sia responsabile di sovraccarichi, poi non so..). Cercando una soluzione ho installato laptop-mode-tools e settato, insieme a indicator-cpufreq per avere alte prestazioni solo quando lo necessito e thermald. Così le ventole non si sono fatte più sentire.
Sempre però che a riposo la temperatura della cpu è intorno ai 60° e con un film in HD è arrivata a 77°.. E' alta a 87° (10 soli gradi centigradi in più), critica a 105. Ma 60-75°C mi sembrano comunque alti. Non oso immaginare con il CAD3D che non ho ancora provato. Comunque da top risulta che indicator-cpufreq, lm-sensors e thermald usano non più dello 0.5% di CPU.
Cambio titolo alla discussione e chiedo gentilmente l'aiuto dei pro.

[JHKevlera]

Per quanto riguarda i driver proprietari, non so proprio come muovermi per trovarli e installarli.

[jackynet92]

Tra wiki e forum trovi molto. In driver aggiuntivi non hai nulla?

[noel80]

Nell'acer lm-sensor mette alta partendo da 70 gradi ... comunque c'era una sola scheda madre che ha avuto problemi con lm-sensors
wiki lm-sensors

Problema relativo alla scheda madre AM2RD790

... in ogni caso ora il portatile si comporta del tutto differentemente , prima pure qui le ventole impazzivano , e la temperatura rimaneva alta ( ora non ho installato lm-sensors ma c'è una differenza notevole che si setiva prima , dalla presa d'aria laterale ) .
In pratica qui ho solo installato i driver , dalla wiki di ubuntu , della scheda video ( non quelli dei repository ma l'ultima versiione del sito , in questo caso AMD ) , e settato tutto in prestazioni , anzichè qualità .

Comunque appena acceso il pc la CPU è a 40°C, dopo pochi minuti sale a 50° usando solo firefox, poi si assesta sui 60 se non faccio nulla di particolare..

[jackynet92]

Se resta sui 60 non è malaccio. Dopo i 70 inizia ad essere problematica. Comunque sembra che tu abbia i driver corretti.

[JHKevlera]

Con un film in HD arriva a 76, non immagino se lo metto davvero sotto sforzo..
Come posso risolvere il problema?

[jackynet92]

Non ti saprei dire, personalmente ho abbandonato unity da qualche anno, "appesantiva" molto il pc....

[noel80]

Anche queste penso si possan prendere in considerazione : ventole raffreddamento portatile .. in ogni caso non credo che windows faccia girare un film in hd rimanedo tanto fresco ... diventan bollenti pure i portatili con windows ....

[JHKevlera]

Ci do un'occhiata. Quindi Gnome 3 oltre che più bello esteticamente è anche più leggero?

[jackynet92]

Per l'esperienza che ho avuto io ti dico di sì.
