In this post you will learn how to lower CPU temp and prevent computer overheating with these easy to use free tips.

How Hot Is too Hot For CPU and other PC components?

PC temperature varies with hardware component. That is each PC part has different temperature range. For example i7 CPU temperature can get up to 105 degrees C whereas, hard drives have a lower operating temperature of 70 degrees C. So you can use different measures on each hardware to prevent computer overheating.

While focusing on computer overheating you should also keep an eye on how hot should my GPU be? As already said that it’s also one of the main cause of computer overheating.

So when you play games the normal GPU temperature should be around 60-80 degree C. If it exceeds from 80 C then it will cause GPU overheating. The idle GPU temp must be around 45-63 degree C.

You should also monitor GPU temperature using best temp monitoring software so that you can prevent graphics card overheating.

How PC Keeps It Cool To Prevent Computer Overheating

All PC cooling system whether they are desktop or laptop computer, dissipate heat out of the computer’s case with the help of several PC fans. These computer fans are the main computer system cooling parts.

In case, hot air is not removed properly, the computer overheating problem can get so serious that it can cause damage to your PC. Therefore, its advisable to monitor PC temperature regularly, although keeping your computer cool should be a top priority.

How To Prevent Computer Overheating

Here are explained best eleven solutions to prevent computer overheating. Most of them are free or some are little inexpensive. So, there’s really no excuse to left your computer overheating while there exists easy DIY tips to prevent computer overheating. Apply these methods to keep your computer cool and lower PC temperature.

Allow for Air Flow

prevent computer overheatingThe easiest way to prevent computer overheating and to keep your PC cool is to give a little breathing room by removing any obstacles to air flow.

To improve air flow there should be 2-3 inches wide space around your computer. Specially take notice of the back side and make sure there’s nothing sitting at back to block air. You can also place external computer fan to provide more air flow in system.

In case, your computer is kept inside desk then make sure the door isn’t closed all the time. Because cool air enters from the front and sometimes from the sides of the case.

If the door is closed all day, hot air tends to recycle inside the desk, getting hotter and hotter the longer the computer is running causing computer overheating.

The fans inside PC cool the whole inner hardware and prevent CPU overheating but sometimes fans gets sluggish. Do you know what causes fan to slows down and then eventually makes it stop?

Dirt, dust, debris and pet hairs– etc. clogs up vents and fans and traps hot air resulting computer overheating. No matter how modern or spacious the PC case is, the dust always finds a way into your computer and much of it gets stuck in the several fans making computer fan loud and noisy.

To prevent computer overheating it’s best to regularly clean PC parts. For that you’ll need a can of compressed air, a microfiber cloth, 99% isopropyl alcohol.

Now open your computer and clean each and every fan in your PC. It includes your CPU fan, external fans, and your power supply fan.

Blast them with a can of compressed air to get rid of dust, and clean the blades with alcohol socked cloth.

Before applying this method, shut down your computer and take it out side in open space. If applying this method you can’t get positive result then it might be broken PC fan.

Take it out and replace it with after market PC fans. The Noctua, Corsair and be quites’s fans are the best PC fans manufacturer.

Set Higher Fan Speeds

prevent computer overheatingDefault fans speed settings is another cause of computer overheating. Usually fans run too slowly to actually cool down PC. Then there is GPU, another heat generator in computer, it’s software only activates the GPU’s fan under certain load range. In order to gain control over fan speed, program like SpeedFan is the best PC fans controller software.

This PC fan controller allows its users to manually increase or decrease fan speed. Just click on up arrow to increase the fan speed percentage. Keeping every fan speed around 50% will keep your PC run at cool temperature and helps you prevent computer overheating.

You can also check PC temp and maintain safe CPU temperatures of your computer using SpeedFan. But there are also other software which can monitor PC fan speed.

Improve Cable Management

prevent computer overheatingThe hardware cables take a fair amount of space in your PC. In case, these cables are strewed around they causes computer overheating because proper air flow is obstructed due to their intermingling. To overcome this issue, zip-tie, move, and configure your cables to create more free space inside your PC.

It sound risky while managing component cables, so always turn off your computer before applying this method. Cable management requires unplugging components and plunging them back in. Yet, taking the plunge will contribute to easier component replacement, better airflow, and overall cleaner look.

Install More Case Fan

prevent computer overheatingInstalling more case fans also solves computer overheating problem. But this methods can cost you 10 to 20 $. More PC case fans installed in your system means more air flow. A case fan is a small fan that attaches to either the front or the back of a desktop computer case, from the inside.

If you want to check the prices of best case fans then pcpartpicker is best place for that. On the other hand, Noctua cooling fan, Corsair high performance single fan, Rosewill case, Be Quiet, Thermaltake quiet computer case Fan are considered best case fans for PC.

The sole purpose of computer cooling fans or case fans is to help move air through computer. The fresh air reduces the chances of computer overheating besides, it’s is a best way to ensure that those expensive PC parts don’t get overheat.

At least, Install two case fans, one at front and other at back of computer to properly move air. These Case fans are easier to install as compare to CPU fans, so don’t be afraid to get inside your computer to tackle this project.

Unfortunately, laptop computer do not have the option to add case fans, but for them an efficient cooling pad is best choice to avoid computer overheating.

Stop Overclocking

prevent computer overheatingAnyone who has knowledge about overclocking can tell you that it causes more computer overheating issues. Why? Because overclocking pushes your computer’s capabilities to its limits and causing rise in CPU temperature and other hardware component.

But if you have already overclocked you computer without providing adequate cooling system then there are chances that your system might die due to computer overheating. So use underclocking techniques.

If you do not understand what is overclocking? Then you probably don’t know about overclocking which means you are in safe zone.

Upgrade the CPU Cooler

prevent computer overheatingAmong other, CPU is the most sensitive as well as expensive part inside your computer. It also has the most potential to overheat. If you upgrade any fan in your PC it will automatically cool all other parts providing better airflow.

But wait, do i need a CPU cooler because when you feel computer overheating in your system it doesn’t mean that by upgrading CPU cooler it will go away. The CPU cooler should only be replaced when you have applied other free computer cooling solution.

Many companies sell large CPU cooling fans that help keep CPU temperature lower than a factory installed CPU fan. These companies offer two kinds of CPU cooler, air or liquid. CPU air cooler come is large and in small heat sinks.

The large one absorbs more heat due to large surface area of heat sink. Before springing for the largest cooler, just make sure that CPU cooler will easily fit in your computer case. For tip Corsair Hydro Series, DeepCool, MasterAir Maker 8 and MSI CPU Core FrozR L Cooler makes the best CPU fans.

Replace the Power Supply

prevent computer overheatingAnother computer cooling solution through which you can prevent computer overeating is to upgrade power supply unit. Because power supply has a larger fan built into it. When you hold your hand behind computer, you can easily feel constant air flow, it is coming from that fan.

If you don’t have a case fan, the power supply fan is the only way that the hot air created inside your computer can be removed. Your computer can heat up quickly if this fan isn’t working properly.

Unfortunately, you can’t just replace the power supply fan. If this fan is no longer working, you’ll need to replace the entire power supply to avoid computer overheating.

Install a Water Cooling Kit

prevent computer overheatingThis method is quite costly. So. use this methods only when you have already applied above methods. Water cooling kit is only feasible in high end computers. Because in these computer, overheating become such a problem that even the fastest and most efficient fans can’t cool the PC.

In these cases, installing a water cooling kit can help a lot to reduce computer overheating problem. Because through water heat transfers efficiently which drastically reduce CPU temperature.

The water cooling system in PC, don’t require much space around the CPU. Liquid Coolers absorb heat through specific liquids then this liquid is cooled using a large radiator mounted within or outside your case. Liquid coolers are easy to install, even if you’ve never upgraded a computer before.

Install a Phase Change Unit

prevent computer overheatingPhase change units are the most useful of cooling technologies. A phase change unit can be thought of as a refrigerator for your CPU. It utilizes many of the same technologies to cool or even freeze a CPU.

Phase change units like the one pictured here range in price from $1,000 to $2,000 USD. Similar enterprise-level PC cooling products can be $10,000 USD or more!
