Fan Replacement and the Dell XPS 8300

Hi I am new to the community, made an account to ask a question because the people around here seem pretty good with computers. I've been looking around for a new back exhaust fan for some time because I got a new GTX 770 and a Corsair TX650(Which has coil whine -_-). I want to make sure that I have enough airflow to avoid any problems with overheating. My question is actually multiple questions regarding fans in general, and replacing a fan on a Dell XPS 8300 desktop.

1. I have never replaced a fan before. How hard is it and are there any general tips? Do I even need a new fan or extra fans?

2. Will the XPS allow me to change the back stock fan that comes with it? (Ive heard some people say that their computer will give them error messages when the fan is replaced, or it wont start up at all.)

3. What are some good fans in regards to CFM? (They don't have to be silent, but the quieter the better. Price isnt too much of a problem either. All of the threads I looked at regarding this are 2+ years old.)

4. Would it be okay to Velcro fans to the inside of the case right behind the lower grate as intake fans or would that mess with something?(Picture:

Ive got:
I7 sandy bridge 2600k 3.4ghz
Corsiar tx650
Standard Dell MOBO
2TB harddrive
4 3 gb ram sticks

  1. 1 Fans are nromally easy to change, make sure it's the right way around though! Do you need one? Depends whether your 770 exhausts heat from the rear of the card or into the case.

    2. No idea

    3. Scythe fans are pretty popular.

    4 don't see any reason why not!

    1. Changing and adding fans is a very easy job. The biggest issue you may have if you add fans is simply are there enough connectors to power them.

    2. I'm not familiar with an XPS but fans are usually simply secured by 4 screws (one at each corner . . . usually self tapping type) and replacing them is simply a matter of undoing the screws, disconnecting your fan. replacing it with a new one and using the screws to hold it in place - basically if you can turn a screwdriver clockwise and anti-clockwise you can change a fan. If you replace a case fan it should not cause an issue with not starting. The only issues you could get would be if you disconnected the CPU heatsink fan. This may sound obvious but on;y change your fans when then computer is switched off - when it restarts the computer won't see any difference between the new fan and the old fan. Worst case you go into the bios to change the fan recognition settings (I use water cooling so had to turn off the feature in the MB bios that recognized I did not have a CPU fan) - easy to do. You have to replace fans with the same size that is there unless your case has drilling to accommodate larger fans (which is not that likely with a pre-built computer).

    3. I use Noctua fans - ugly colours but work well, very quiet and have a 5 year warranty . . . . but they are expensive. The main consideration is the fan speed - the faster they go the more air they move but the noisier they get - I tend to use larger slower fans - usually at least 120 mm wherever possible but keep speeds to 1500 rpm or less. 3000 rpm fans grate on the nerves !!!!!

    4. I've never Velcro'd fans personally . . it might work but you could also drill some holes (assuming you are drilling into metal). Velcro may work fine - nothing to stop you from trying it . . . . . worse case find something a bit more permanent :)

    Welcome to the world of computer building . . . its fun (and sometimes quite frustrating especially when you find your i7-4770K won't exceed 4.1 GHz even with a very fancy ASUS Maximus Formula Vi motherboard :(

    ps per mi1ez - Scythe are also pretty good fans
  3. Just curious, did you happen to upgrade your cpu heatsink and fan? If so what did you upgrade it with and what problems did you encounter if any. I have a dell xps8300 i7 that i want to upgrade my cpu but have not found anyone who successfully did it and wrote about it on the internet. Thank you.
