Overheating Problem

[fluke83]

Hello everyone. First of all, thank you for taking a glance at my thread & hopefully able to help me out a bit. (i luv this site)

I have a Dell Studio 540 desktop & I recently upgraded my graphics card to an ATI Radeon 5770, everything else is factory. Now, after I've been gaming for a few hours, the fans really start to wind up, & the air coming out the back gets pretty warm. Sometimes the game even slows or gets jerky. When I crack open the case, air inside doesn't necessarily feel hot, not even around the graphics card. I really need to get this overheating issue under control ASAP because FINAL FANTASY XIV comes out Wednesday, so I'm sure I'll be spending alot of time on the game.

I do know one thing, my power supply is being pushed pretty hard. Rated max 350w & PSU calculators recommend 325w for my system (280w min). A guy with GeekSquad told me a bigger power supply should solve the problem because they have bigger fans that take out the hot air.. Also, I know Dells aren't built for good airflow.

So, I was thinking of upgrading my PSU to maybe a 750w? Since I'm going to upgrade rest components/case in a couple years when I got $$ instead of buying a new PC. Now, I got about $100 to deal with this heat problem. So, do you guys think I'm on the right track? Do you have any other recommendations to rid the heat ?? And most importantly, I've heard Dells have trouble fitting in larger PSUs. Has anyone put a bigger power supply in a Studio 540 before ???

My factory PSU Model: ATX0350D5WA Rev.:A00 measures at 6"wide x 3.5"tall x 5.5" long

Thank you so much, again. Peace

if its cool in the case and hot air is coming out of the psu you are likely overworking that psu, so yes a new psu should resolve the problem

the case is cool so you do not need more air flow, if you did a new case fan would be the solution not a new psu

imho 750watts is a bit excessive

I guess I it might be helpful if I mentioned the components:
Intel Core 2 Quad Q6600 2.4GHz
Memory - 6GB DDR2
GPU - ATI Radeon 5770
optical - Bluray/DVD-R combo
1 HDD
Front Bay Card Reader
Wireless Network PCI Card

Sorry Mr. "505090" that last reply wasn't directed to u, I was just adding it to the post...lol

But, thanks for giving some imput. I was just thinking a PSU that high because in the future when I get a new case I'll be doing some overclocking/upgrading, maybe crossfire another 5770 to run games on max settings. Plus who knows what technology will deliver for us to put in our PCs in a few years.

Also, would getting a new case fan actually help overall cooling? Cuz only another 80mm would fit in its place. After all, for something that cheap it can't hurt.

if you are going to go with crossfire 5770 you only need 600watts, but a little extra won't hurt

for overclocking quality is much more of an issue than quantity, go with a good brand

if all your fan slots are full and working i wouldn't bother messing with them
