Raid 0 on C: drive - CPU getting hot

Hi all, I recently reimaged my PC and got two 120gb SSDs and used raid0 on them and installed windows on that volume. ever since I did this, there are certain things I run on my PC that makes the CPU to hot and reports temperatures of 70 degrees celcius or hotter. These processes I run are doing a full virus scan on my drive, even doing a quick virus scan, converting RAW files (image files) to JPG. When just had one hardrive as my C: drive this never happened. does using a raid 0 as my C: drive cause the cpu to work harder?

While raid0 would increase your cpu usage a percent or two I feel that the main cause of the heat increase is that now the CPU can run at a higher level thanks to the ssd's and in doing so it has revealed a weakness in your cpu's cooling.

First step would be checking all the fans and making sure they are all working, next make sure the cpu cooler is attached securely at all 4 corners (sometimes a corner likes to come loose) and not clogged with dust. Next look at the whole pc and how cool air is getting drawn in and hot air being expelled. The hot air should be dissipated thru the whole room and not allowed to be sucked back in. (ie: dont put the pc in a desk cabinet or closet.)

Next, if you have the stock cpu cooler, remove any cpu...

I don't have any data on my C: drive. so why do you think the cpu is getting to hot when running the processes mentioned?

Outside of a few edge cases, RAID 0 on SSD's provides no benefit. The only thing it brings is a greater potential for fail, and greater complexity.
 


because of instead of just reading data, it's got to read two streams of partial data and stitch them together to form the actual data that you need. RAID5 for instance it's got to calculate the parity data as well.

And I presume you have the OS, the programs, are you using it as scratch space, is your swap file on there?

Yes I have my OS on there and yes I have my swap file on there. I don't know what scratch space is. I have my OS installed on this RAID 0 volume the same way I'd install it on any other single HDD.

The software I use to convert the RAW files to JPG is on the raid0 C: drive. The raw files themselves and the JPSs are on a seperate HDD.

What software is it?
 


And the temp folder that your software uses is where?

It certainly won't make it any cooler.
The system has to do extra work, striping across the two drives. Work = heat.

Since you only variable was single drive vs the two in RAID 0...that may well be your issue.

It is the exact same space, RAID 0 or no RAID 0.
120+120.

All you may have gained was a single drive letter -C- instead of a C & D.
I had a 120GB SSD as my boot drive for a looong time. A lot of photo work. Never had a space problem, because I caused stuff to go elsewhere.

it starts warning me when it reaches 70 degrees. a couple of times it reached 80 degrees. I'm not sure if its celcius or fahrenheit
It have the i2600k cpu using stock heatsink/fan.

Next, if you have the stock cpu cooler, remove any cpu overclock that you have and enter the bios and make sure the cpu voltages are all back at stock values and that you don't have any automatic overclocking going on. The stock cooler is good but its only enough for a small overclock.

Let us know how you make out.
