First off, Ive never had a 7200RPM HDD, is it significantly faster than the 5400RPM? (computer specs below)

Mainly though, I am looking to purchase the Gigabyte P34G laptop which apparently has fan/cooling issues. It actually cools quite well since it has two fans but when the fans turn on apparently they sound like "jet engines" so I want to make sure not to exacerbate that issue with a hotter HDD.

So im customizing my laptop at and will pay extra for their "IC Diamond Thermal Compound - CPU + GPU" (is this worth it/actually do anything- its $25) and for the storage system, by default it comes with this spec'd:
128GB mSATA SSD + 1TB 2.5" 9.5mm HDD 5400rpm
But im debating getting the 7200RPM version of the HDD, Its $89 more and might be worth it to me in regards to its speed, but in general i want to keep the temperatures low to keep the fans from kicking in more often than needed.

Will the 7200RPM HDD increase overall system temperatures compared to the 5400?

All help much appreciated, buying a new laptop is quite an investment! Thank you!

Honestly in everyday performance I never saw a difference in my laptops 5400 rpm vs 7200 rpm drive. I even had a 7200 as my desktop and got a new WB Blue which is 5400 RPM and i still don't see a difference in. If you are coping big files around then yes you will see a difference.

Now the whole 6Gpbs vs the 3Gbps. That really only applies to SSD's. I have some 2TB Samsungs 3Gbps 5400 Rpm and some 2TB WD Reds which go from 5400-7200 depending on how they are being used. Now i have tired the WD Reds on 3 and 6 Gbps and I didn't see a difference in speed and I there is very little difference in speed compaired to my Samsung drives.

Thats just from my expereices.

thanks drtweak, i went with the stock 5400 for exactly your experience, as many seem to share it.

Also a lot of it is about Platter Density. When you compare a 7200 RPM to a 5400 RPM or even a 10k or 15k drive they have to be the same size, same amount of platters and what not. If they are different in any way you can't really compare them. Its like Trying to compare cars.

Same model but you got a 4, 6, and 8 cylinder engines for the same model. You know the 8 is gonna be more powerful while everything else is still the same. Handeling, turning, ect.

If you compare like a Corvette to a Mustang well then its hard to because its a whole different car and everything is different. They can have similar horse power (RPM Speed in this case) but one could still be more powerful than the other.

I knew of a really good article on this for long ago but can't find it. I know my boss was all big about these 10k and 15k SAS drives but its like if you get a 160 or 320 gig drive compared to a 1TB 5400 RPM drive they read and write speeds are the SAME! so yea not a huge deal and unless you in the market of moving large amounts of data very quickly then there isn't a huge need for 7200 over 5400 RPM.

yea i wanted to look into platter size but the stock options had no spec info (brand, model etc) it just had rpm and gb/s. all the expensive upgrades had info about exactly which HDD you were getting though (of course).
