Hot ThinkPad X100e : mengontrol putaran fan prosesor dengan Thinkfan

Pada awal saya menggunakan notebook ThinkPad X100e dengan OS Ubuntu, kesan minus pertama kali yang saya dapat adalah suhu prosesor yang panas. Sangat panas. Pada awalnya saya berasumsi positif bahwa ini memang ciri khas prosesor AMD Athlon Neo MV-40 1.6 Ghz.

Tapi setelah saya menginstall beberapa aplikasi monitoring suhu komputer seperti GNOME Sensors Applet dan AWN Hardware Sensors applet tercatat suhu prosesor saya 75°C, bahkan kadang tembus 90°C !! Ffuuih ... tinggal dikit lagi hampir sama dengan titik didih air!

Logika saya, hal ini tidak baik buat usia hardware notebook ini. Setelah browsing 2 hari di internet, dapat kesimpulan bahwa fan untuk beberapa type ThinkPad bisa diatur speed-nya lewat aplikasi kecil bernama ThinkFan. 

WARNING !! Do it at your own risk!
Prosedur ini sangat beresiko. Saya tidak bertanggung jawab jika terjadi kerusakan pada hardware anda.

Untuk instalasi dan setting saya mengetikkan perintah berikut di Terminal

sudo echo 'options thinkpad_acpi fan_control=1' >> /etc/modprobe.d/thinkpad_acpi.conf


sudo echo 'options thinkpad_acpi fan_control=1' >> /etc/modprobe.d/options


sudo apt-get install thinkfan

 
Lakukan reboot, langkah selanjutnya saya edit konfigurasi thinkpad.conf, caranya sebagai berikut :

sudo gedit /etc/thinkfan.conf

edit file tersebut dan masukkan nilai-nilai berikut :

sensor /proc/acpi/ibm/thermal (0, 10, 15, 2, 10, 5, 0, 3, 0, 3)
(0,    0,    55)
(1,    48,    60)
(2,    50,    61)
(3,    52,    63)
(4,    56,    65)
(5,    59,    66)
(7,    63,    32767)



Simpan, lalu coba aktifkan thinkfan dengan perintah berikut (lumayan kaget, fan notebook mendadak berputar cepat, itu artinya berhasil hehe..) :

sudo thinkfan


Langkah terakhir, supaya service thinkfan ini berjalan pada tiap kali boot notebook, saya lakukan langkah berikut :


sudo gedit /etc/default/thinkfan 

lalu ubah nilai pada START=no menjadi START=yes


Oke sekarang service thinkfan sudah berjalan dengan baik di X100e saya. Perbedaan yang jelas terasa, tentu saja notebook ini menjadi lebih dingin dari suhu 75°C sekarang rata-rata suhunya stabil di 55°C dan kipas prosesor menjadi lebih 'sibuk' dan sedikit bising. Well, menurut saya lebih baik bising tapi dingin daripada diam tapi panas, ya gak?

Kalaupun clock + suhu prosesor naik (karena menjalankan aplikasi yang berat), sang kipas juga otomatis akan menaikkan putarannya, keren kan?

Catatan :
  1. Dalam melakukan percobaan ini saya menggunakan referensi dari thinkfan, thinkwiki, Debian User Forum, Netaddict, PC-Freak. Saya sarankan untuk membaca link-link diatas terlebih dahulu. Result may vary
  2. Saya menggunakan Ubuntu 10.10 (64-bit) kernel 2.6.35-23-generic
  3. Jika anda pengguna OS Windows, maka trick ini bukan untuk anda.
  4. Beberapa tulisan di internet, trick ini juga bisa diterapkan pada ThinkPad Edge. 
  5. Daya tahan battery lebih lama. Saya tidak punya angka pembanding pasti, tapi by feeling terasa peningkatan.

  3. It's the Millennium boxing match or an abomination that spins in a cross code, but what we can say with certainty, in the end, is that it's happening. Once retired all-time great boxer Floyd Mayweather will take UFC star Conor McGregor in Las Vegas.
    There has been what it feels like years of speculation about the fight, with so many name calling on both sides. But the two fighters have announced that it is in fact, in.
    Yes, that's right, a boxer with a 49-0 record against a man who has never taken part in a professional boxing matchup.
    Anyway, here you have everything you need to know about the McGregor vs Mayweather fight.

  6. The UFC originally intended an interim title bout between Nurmagomedov along with The Ultimate Fighter: Team Lesnar vs. Team dos Santos welterweight winner Tony Ferguson, however, it had been canceled due to the Russian together with medical issues connected with his weight reduction weigh-in day.Ferguson eventually won the interim name at UFC 216 against Kevin Lee.Ferguson was then predicted to fulfill Nurmagomedov in UFC 223, together with the winner being crowned the undisputed winner (because McGregor could be stripped of this title if the bout happened). Subsequently, it was scrapped once more (fourth moment) since Ferguson got hurt, and after several opportunities to acquire an opponent, Nurmagomedov eventually won the vacant title against Al Iaquinta. [9] [10] This card has been marked by an attack on a bus containing a number of fighters scheduled to compete at the event (like Nurmagomedov and 2 teammates), ran by McGregor and his group.

    Jussier Formiga was formerly scheduled to face Sergio Pettis at January 2017 in UFC Fight Night: Rodríguez vs. Penn.. But, Formiga pulled in the struggle for undisclosed reasons.The pairing was rescheduled for this particular occasion.
