  • Many casual computer users are discovering that they do not need the power, functionality, or expense of a full-fledged laptop. Meanwhile, a tablet lacks the large screen and dedicated keyboard needed to consume different types of media or to browse the internet. A Chromebook splits the difference neatly, and may well be the best choice for most consumers looking for a more affordable device.What started out as an underpowered curiosity has evolved into a category of its own. Chromebooks typically cost less than a Microsoft Surface or MacBook, but the primary drawback is that Chromebooks are limited to Chrome OS. Start-up times are a snap thanks to the light interface, but Microsoft or Mac programs won't work outside of the Chrome browser unless there are online app versions available. Another reason to recommend a Chromebook is because they are not as susceptible to viruses and malware thanks in part to continuous automatic updates to Chrome OS. If you are looking for a Chromebook, keep reading for the best Chromebooks in 2021 we recommend for every budget.

  • While a surge protector might seem like little more than a fancy power strip, the protection they provide can be crucial for guarding your electronic devices. Their protection is usually rated in Joules, which is a measurement of energy and indicates how much of a surge they can protect against; generally a higher rating means more protection from one of these devices. It’s important that any power outlet in a house or similar building be properly grounded to ensure a surge has somewhere to go, even with a surge protector in place. The immense power of a bolt of lightning cannot be adequately handled by a surge protector, but good protection can deal with more common power issues like surges utility provider or other local sources. Read through our list of the best surge protectors in 2021 and the surge protector buyer’s guide below for information to help you pick the best model to safeguard your setup.

  • I've been overclocking computers for over fifteen years and I can tell you first hand that thermal compounds have come a long way in that time. They are an important component of any computer build as it can make the difference between a heatsink or water-block installation that is outstanding or one that is merely average. The compounds for this list are all non-conductive pastes so problems such as shorting out your CPU or other components will not be an issue. All of them also have very high thermal conductivity for good heat transfer as well as yielding low delta temperatures (Delta T) under CPU stress testing; delta T is the amount in degrees of temperature rise above CPU idle temperatures exhibited by the CPU when at one hundred percent load. All of the best thermal compounds in 2021 on my list have Delta T ratings of no more than 33 degrees Celsius. Finally, all of them are formulated to be convenient to apply and easy to clean up.

  • When it comes to CPU cooling, there are two basic designs you can look at and choose from: liquid-cooling and air-cooling. In either system the goal is simple: to transfer heat away from the CPU in your computer and dissipate it through liquid or air. Both liquid and air-cooling systems work great and can help keep your CPU within safe performance conditions. These are primarily high-end products that are great for powerful computers and work well for overclocked systems that can produce higher heat than some other setups. Some of these models are fairly large so look at their listed sizes and your computer tower to be sure you have space enough for the cooler in your system. We've gathered the best CPU coolers in 2021 and these CPU coolers reduce heat efficiently thanks to fans that spin at rates of at least 1200 RPM for optimal performance. The fans that run in these coolers are at least 92mm in size, which helps provide at least 45 CFM of airflow, though many of these offer much greater performance. They run quietly with a maximum noise level of no more than 40 decibels (dBA).
