T here is an excellent little utility to monitor hard drive temperature. Most modern computer hard disk including SSD comes with S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology). It is a monitoring system for computer hard disks to detect and report on various indicators of reliability, in the hope of anticipating failures. Hard disk manufacturers often state the operating temperatures of their hard disk drives to be between 0°C to 60°C - This can be misleading because what they mean is that your hard disk will function at these temperatures, but it doesn't tell you anything about how long they are going to survive at this range.

What is a safe HDD temperature range to avoid overheating and hard disk failure? What is the method way to monitor and lower your hard disk temperature? Get the full answers right here.

For years, overheating has been blamed as the main culprit for drive failures and while it made perfect sense on paper, there were no hard facts from large-scale studies to support that belief.

Then Google came along and published 'Failure Trends in a Large Disk Drive Population', a research paper that some consider to be the Bible of HDD failure. Pulling data from more than 100,000 consumer hard disk drives, some of its major findings included:

  • Hard disk temperatures higher than 45°C led to higher failure rates
  • Temperatures lower than 25°C led to higher failure rates as well
  • Aging hard disk drives (3 years and older) were much more prone to failure when their average temperatures were 40°C and higher

This study also suggested that the effect HDD temperature has on failure rate is not as severe as previously believed. However, there was no mention of the effect of temperatures higher than 50°C (probably because Google kept their hard disk drives in server rooms with strict temperature controls).

Hard disk manufacturers often state the operating temperatures of their hard disk drives to be between 0°C to 60°C - This can be misleading because what they mean is that your hard disk will function at these temperatures, but it doesn't tell you anything about how long they are going to survive at this range.

How to Check and Monitor Your HDD Temperature

There are a few popular hard disk temperature monitor freeware, but we highly recommend CrystalDiskInfo for a few reasons:

  • Clean, user-friendly interface - If you have multiple hard disk drives, the program makes it easy for you to tell them apart and check their individual temperatures.
  • Alert features - the program will sound a warning alert or even email you if it detects any early signs of hard disk failure.
  • Helpful information - the program also display useful details such as your hard disk serial number, buffer (cache) size and power on hours.

Effective Ways to Lower Your HDD Temperature

If you haven't bought your hard disk drive yet, then the first big step is to choose hard disk drives that operate at lower temperatures.

Manufacturers often tout them as green or eco drives - These drives often spin at lower speeds (5,400 RPM) and have less data platters to minimize hard disk temperature. Popular examples include WD Green drives and Samsung Eco Green drives.

If your existing hard disk drives are too hot for comfort, then one of simplest (and overlooked) methods to lower temperatures is leave a gap between your drives:

This simple step alone has been shown to reduce hard disk temperatures by 2 to 4°C in most cases.

If your hard disk drives are still running too hot, then check whether your computer case has vents that allow you to install additional case fans to blow cool air at your hard drives. Since the hard disk drives are located at the front of most computer cases, it's better to install the fan in the intake direction (blowing cool air from outside into the case instead of sucking hot air out).

Even in this age of solid state drives, hard drives still dominates when it comes to bulk data storage. They are cheap, reliable and come in high storage capacities. Normally, hard drives don’t require additional cooling as they can run on passive cooling without any issues, but in some cases where you have a compact case / slim case or a case with restricted airflow then your hard drives can get very hot. Also, high ambient temperatures can also cause your hard drive to reach higher temperatures that may not be safe for it in the long run. Some high-performance hard drives such as WD Black series naturally run hotter than a standard hard drive, and sometimes cooling may be required for it, even if you have good airflow in the case. Overheating of the hard drive can result in drive failure and thus data loss. So, if you are in such a situation where your hard drive is getting too hot then you need to take some measures to keep its temperature down to normal levels.So, here I am going to list some ways to lower your HDD temperature. Let us first learn about the safe operating temperature of a hard drive and at what temperature you should be worried about it.

Safe Operating Temperature for Hard drive

The safe operating temperature for most of the hard drives is between 10°C to 50°C, but some modern-day HDDs can withstand up to 60°C. However, if you see your hard drive getting above 50°C then it is a sign of worry and you have to take appropriate measures to bring it down. Also, your hard drive should not be running too cold, because in too colder environments, the viscosity of the lubrication between the parts increases, which then increases friction and may shorter the HDD lifespan and can lead to its premature failure. Also, metal parts shrink under much lower temperatures and can cause misalignment between the head and the platters and may lead to a breakdown. In my opinion, it is better to keep the hard drive temperature between 20°C to 40°C for its longer lifespan.

How to Check Hard Drive for Temperature & Errors

To monitor the hard drive temperature and other important parameters, you can use a small utility called CrystalDiskInfo. It is available for free to download and you can get it from the link given below. It can tell you about your hard drive temperature, firmware, serial number, transfer modes, features, power-on hours, etc., and also shows its health status. It can also report errors with your hard drives that include bad sectors, reallocated sectors count, etc. This utility also supports SSD and is one of the best hard drive monitoring tools available.

Ways to Fix Hard Drive Overheating

Here are the following ways to prevent your hard drive from overheating. These tips are applicable to 3.5-inch internal hard drives from any brand, whether it is Seagate, Western Digital or Toshiba.

Install Front Intake Fans

If your hard drive bays are located just behind the front panel (which is in most of the cases) then installing front intake fans can really help to cool down your hard drive and can prevent it from reaching much higher temperatures. It must be noted that front intake fans should be high static pressure fans because they can push a high amount of air in a focused way so that air can even reach in the tight and restricted places. I would recommend installing the maximum number of intake fans at the front panel supported by your PC case. This helps to achieve better airflow inside your case, which will keep the internal components cooler.

HDD Coolers & Fans

The dedicated approach to cool down a hard drive is by using a hard drive cooler. This is an active cooling strategy and by this, you can cool any 3.5-inch hard drive more efficiently. The hard drive cooler consists of a fan that attaches to the hard drive and blows air directly onto it and prevents it from overheating under heavy load or during continuous operation. If you have an SFF case with no provision for a front intake fan then this is the best way to cool down your hard drive. Below are the most practical and good hard drive coolers that you can get online. These hard drive coolers are slim, take up very less space and are very easy to install onto a hard disk.

Scythe Ita Kaze HDD Cooler

A slim hard drive cooler from Scythe that comes with a slim 100mm fan, surrounded by a heatsink having aluminum fins. The fan is frameless in design and is integrated with the whole HDD cooler frame and heatsink assembly. The fan comes with sleeve bearing and runs at 1000 RPM. It is very silent and has a rated noise level of 14.5dBA only. This is a 12V fan that uses a 3-pin connector but a 4-pin adapter comes bundled with the cooler, for use with Molex connector. You can control the fan speed by using a fan controller that changes fan speed by varying the voltage or by using a low noise adapter 3-pin cable (7 Volt or so).

The HDD cooler can be attached to the bottom of the 3.5-inch hard drive using the four screws that are included with it. The fan covers almost the entire area of the hard drive and you can expect up to 10 °C to 15 °C drop in temperature on the hard drive. The installation of the cooler is quite effortless on the hard drive but installing the hard drive using this cooler in modern cases can be a challenging task because nowadays most of the cases use tool-free and quick release clip mechanism / mounting trays for the hard drives. So, you have to figure out a way to install the hard drive in your PC case with this HDD cooler attached. This lightweight hard drive cooler is very affordable and its model number is SCIT-1000.

Scythe Kaze Jyu Slim 100mm Fan

This is merely a 100mm slim fan (12mm thick) that comes with a hard disk mounting kit, to be used as a hard drive cooler too. The fan has got the same specifications that are found in the fan present on the Scythe Ita Kaze HDD Cooler.

The mounting clips allow the fan to be installed on the bottom of a 3.5-inch hard drive. It cools down the hard drive to almost the same level of the above-mentioned Scythe HDD Cooler. The fan has got 92mm screw holes too, which allows it to be used in SFF computer cases with 92mm mounting points. This is a 3-pin 12V fan and a 4-pin Molex adapter comes included with it.

Note: A 2000 RPM version of this fan is also available, which you can also check out from the link given below. This higher RPM fan is not quite a silent performer and has a noise level rating of 29dBA, but it generates more cooling and airflow.

Fix HDD Overheating for Laptops

Check Hard Disk Temperature

2.5-inch Hard drives in laptops can get pretty hot (hotter than PC HDDs) under continuous operation because of almost no airflow in the laptops for the hard drive. In PC, you can install a hard drive cooler or additional fans inside the case to cool it down to safe levels, but in laptops, you cannot do so. So, the best way to cool down a hard drive in a laptop is to use a good laptop cooling pad or laptop cooler.

Note: When working, always put your laptop on a flat hard surface, so that the vents under the laptop don’t get blocked up. These vents are for heat dissipation and if you put a laptop cooler under it then the fans help to dissipate the heat faster, which then cools down its various components.
