Base details
Website, pricing, platforms and company facts side by side.
Cost SpeedFan is free software, making it accessible to anyone without any financial investment.
Temperature Monitoring Allows users to monitor the temperature of various hardware components, such as CPU, GPU, and hard drives, helping to prevent overheating and extend hardware lifespan.
Fan Control Enables users to manually adjust the speed of fans, providing a balance between cooling performance and noise levels.
Customizable Offers extensive customization options, including automatic fan speed adjustments based on temperature thresholds and the ability to create user-defined profiles.
System Information Provides detailed system information, including voltages, CPU usage, and S.M.A.R.T data from hard drives.
Support for Multiple Sensors Supports a wide range of sensors from various manufacturers, making it compatible with many different hardware setups.
Possible disadvantages
User Interface The user interface is considered outdated and not very intuitive, which may be difficult for new users to navigate.
Compatibility Issues Some users report compatibility issues with specific hardware, particularly newer motherboard models and certain sensors.
Support and Updates Updates and official support have become sporadic, potentially leading to compatibility problems with newer hardware and operating systems.
Stability Users have experienced occasional stability issues, including crashes and incorrect fan speed readings.
Learning Curve Due to its extensive functionality, there is a steep learning curve for users who are not familiar with hardware monitoring and fan control software.
Potential Risks Improper use of manual fan control settings can potentially damage hardware components due to overheating or excessive strain on the fans.
No-code website modifications Modify allows users to make changes to their websites without needing to write code, making it accessible for non-developers who want to customize their web presence quickly.
Easy A/B testing and personalization The platform enables users to run A/B tests and personalize website content for different audiences without requiring developer involvement, speeding up optimization efforts.
Quick deployment Changes can be deployed rapidly through Modify's interface, bypassing the traditional development cycle and reducing time-to-market for website updates and experiments.
Visual editor Modify provides a visual editor that lets users point-and-click to make changes on their site, making it intuitive and reducing the learning curve for new users.
No impact on site codebase Since modifications are applied as an overlay rather than directly changing the source code, the original codebase remains clean and unaffected, reducing the risk of breaking existing functionality.
Possible disadvantages
Limited awareness and community Modify is a relatively niche tool with a smaller user base compared to established competitors like Google Optimize or Optimizely, which means fewer community resources, tutorials, and third-party integrations.
Performance concerns Applying modifications via a third-party script layer can introduce additional page load time or cause flickering effects as changes are rendered on top of the original page content.
Limited customization depth While the no-code approach is convenient for simple changes, more complex modifications or deeply integrated features may still require developer intervention, limiting what can be achieved through the platform alone.
Dependency on third-party service Relying on Modify means your website changes are dependent on their service uptime and continuity. If the service goes down or shuts down, applied modifications could be lost.
Potential SEO implications Client-side modifications applied via JavaScript overlays may not be fully recognized by search engine crawlers, which could lead to discrepancies between what users see and what gets indexed.

Question - Are the loading times supposed to be this bad right now??
That's not super common (but it does happen ofc). It might be worth running a tool to scan the drive and take a peek at the SMART data. I typically use Speedfan https://almico.com/speedfan.php.

Computer has come back from a repair shop wiped and is missing A vital app I used to control fan speeds and I cant redownload it. Any alternative apps?
You'll get better gpu support from Afterburner, but if you have a weird chipset or an incompatible fan controller, good old SpeedFan still has a few tricks.
