Cooling Solutions for the Raspberry Pi 4: Optimizing Performance and Temperature

The Raspberry Pi 4 is a powerful single-board computer, boasting a 1.5GHz Quad core Cortex-A72 processor that makes it the best-performing Raspberry Pi to date. However, with great power comes the great responsibility of managing its temperature.

During intensive applications, the Raspberry Pi 4 may get quite hot, with the CPU throttling at around 80 degrees to protect itself. To optimize the board's performance, it's best to keep its temperature as low as possible. Therefore, we conducted some stress tests to evaluate the performance of our new XL heatsinks with and without a fan case.

In the first test, we ran the Raspberry Pi 4 with no cooling solution. It reached a maximum temperature of 82 degrees, beyond the throttling threshold, and its CPU frequency dropped to 1GHz. This test indicated that a cooling solution is necessary when pushing the Raspberry Pi 4 to its limits.

In the second test, we tested a large heatsink alone to see if it could keep the Raspberry Pi 4 below the throttling temperature. The result was a maximum temperature of 75 degrees, indicating that silent cooling without throttling is possible with a large heatsink.

For the third test, we used the Raspberry Pi 4 Case (with Cooling Fan) (v2.0) in an exhaust configuration with and without our large heatsinks. The fan was connected to the board's 5V line and maintained a constant speed. The maximum temperature was 61 degrees, dropping to 56 degrees with the addition of the large heatsink. The quieter fan reduced the CPU temperature by 21 degrees when exhausting heat, and the large heatsink helped reduce it by an additional 5 degrees. Overall, this combination proved to be cool and quiet.

In the fourth test, we flipped the fan around to an intake configuration, sucking air into the case and directly onto the CPU. This test resulted in a maximum temperature of 57 degrees, dropping to 51 degrees with the addition of our monstrous heatsink. Simply flipping the fan over helped reduce the temperature by an extra 4 degrees.

In conclusion, these tests highlight the importance of having a cooling solution for the Raspberry Pi 4, especially during intensive use. With a large heatsink and a fan case in either an exhaust or intake configuration, the Raspberry Pi 4 can maintain optimal performance with low temperature and minimal noise.

Cara Disable Antimalware Service Executable di Windows 10

Disadari atau tidak, Windows 10 (dan juga windows-windows lainnya) hadir dengan banyak sekali aplikasi bloatware (aplikasi yang tidak perlu-perlu amat dimiliki oleh end user). Contohnya, adalah aplikasi yang seharusnya sudah tergantikan fungsinya oleh antivirus, seperti Antimalware Service Executable . Aplikasi ini dicurigai membuat Windows 10 mengalami inefisiensi memori/RAM, memakan resource yang tinggi, dengan Load yang tinggi (tanpa limit terkadang). Nah, berikut adalah cara men-disable nya: Tekan tombol Windows + I untuk membuka apliaksi Windows Setting. Pilih icon menu Update and Security Pilih lagi menu disamping kiri Windows Security Pada jendela baru yang muncul, ada pilihan Virus & Threat protection Klik ini Lalu matikan proses Real-time protection tersebut. Dengan Regedit. Buka dialog regedit, Windows + R dan ketik ‘regedit’ Cari Folder regedit ini HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Buat sebuah DWORD baru dengan klik kanan

Setup Debian 11 Official Repository In sources.list (/etc/apt/sources.list)

When you install Debian 11 using a DVD, the OS installer sets the DVD as the source for getting packages for your system if you didn't choose to scan for network mirrors. Due to this reason, the system would ask you to insert a DVD if the disc is not present in the DVD drive when you try to install any software.  Also, the packages on DVD may not be the latest release.  So, we need to get the packages from the Internet. Media change: please insert the disc labeled 'Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04' in the drive '/media/cdrom/' and press [Enter] The /etc/apt/sources.list file with DVD as a source would look something like below. # deb cdrom:[Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04]/ bullseye contrib main deb cdrom:[Debian GNU/Linux 11.0.0 _Bullseye_ - Official amd64 DVD Binary-1 20210814-10:04]/ bullseye contrib main deb bullseye-security

Cara Membuat Live USB VMWare ESXi 6.7 di Linux (Debian/CentOS)

VMWare ESXi 6.7 menyediakan satu installer dalam format CDROM ISO. Dalam tutorial kali ini kita akan membuat sebuah live USB dengan menggunakan sistem Linux, misalnya Debian dan CentOS. Untuk keperluan tutorial kali ini silakan pastikan sudah ada download installer ISO ESXi 6.7 dari Siapkan satu USB Flashdisk dengan kapasitas lebih dari 1GB. Format dalam satu partisi dengan tool yang biasa dipakai dalam format partisi FAT32. Misal dengan FDISK: [sourcecode] fdisk /dev/sdX [/sourcecode] format ke FAT32: [sourcecode]mkfs.fvat -F 32 -n USB /dev/sdX1[/sourcecode] selanjutnya, kita buat USB tersebut bootable dengan syslinux. Bagi linuxnya belum ada syslinux, silakan install dulu (apt-get install syslinux atau yum install syslinux).
