HDD Temps?

post #1 of 6
Thread Starter 
Both of my HDD's are running about 40-42 degrees Celsius in a HTPC case under load. The issue right now is that there is no fan over these HDD's but they are sitting under a vent where air can pass through. Should I consider moving the HDD's somewhere in my case where I can get air to them?

Its nice to have some airflow over your hdd and if its easy to get some do it. But if your max temps are 40-42c as you say, there is nothing to worry about.

I think I read somewhere that Google had done a test, where they found that the drives were least likely to fail when they were around 41c. I'll see if I can dig it up.

my hdd usually run anywhere between 40c-48c so if the higher you getting is 41c you will be fine.

The Google HDD Study is a little difficult to follow without some statistical analysis. The graph (from the study) that best shows the situation is this one:



What it shows is that during the 6 month to 2 year timeframe, when a hard drive is still in the prime of it's life, that annual failure rate is HIGHER at 30-35 degrees C than it is for higher (35-40, 40-45, and 45C+) temperature ranges. It also clearly shows that as a HDD ages into 3 years and 4 years, that temperature plays a more important role in AFR% and you can see in the graph that "cooler is better".

Looking at the graphs, the sweet spot is 35-40C on average, and 30-35C as drives get older.

I was running a hardware monitor yest to compare temps because I did a few modifications to the case. In the pic below, this is where the HDD's sit right now. I placed rubber circular pads around the screw holes so they aren't fully touching the chassis.

I was thinking of mounting the HDD's above the 2 middle fans are at.

I was also considering moving to a Corsair 350D or 300R just to get better air flow in the case.
