Improving cooling for my PC

I have a Cooler Master Storm Enforcer with its default fans, a 200mm front intake fan and a 120mm reat exhaust fan.

Unfortunately, I have a non-modular power supply which kind of blocks off the front fan; I am worried that not a lot of air gets to the GPU.

Fortunately, the top of the case has an enormous space for 1 200mm fan, or two 120mm fans. Which fans should I get if I want to fill this space out? Should they be exhaust or intake?

Thanks.

I'd also see about zip tying your cables to the bottom of your case, as much as you can, and again, as much as you can, tucking them under the motherboard tray (zip tying them down to keep them out of the way.) While this won't get them out of the way as much as a modular or semi-modular PSU cables would, it can go a long way to clear a path for airflow.

Putting 2 fans up top may not help much tho. Your GPU probably sits pretty low in the case, and what little air is making it to it could just get sucked up and out by the exhaust fans. I would look at a way to improve the airflow TO the GPU at the bottom of the case. You may want to reorganize your wiring.

I'm using MSI Afterburner currently. My fan curve is set so that the fans don't kick in until the GPU reaches 60 Celsius. Once they reach 60 celsius, they run at 50%. Generally in really intensive games, like Hitman at a 1440p downsampled to 1080p and maxed out, I reach the mid 70s. Here, the fans ramp up to 60%

What sort of fan curve would you recommend?

Thanks. I have a CM Storm Enforcer case. Apparently, the HAF 912's side panel (it has a slot for a fan) can fit perfectly on this case. Do you think that it would be worth it to shell out the money for a new fan and a side panel? Would it make a huge difference in temperature?

It's hard to say how that would affect the airflow, for better or worse (I'm running a thermal performance evaluation in my head!). All things considered, your temperatures are reasonable, and I think your biggest improvement would come from cable management and hard drive placement in order to get more air to the bottom of the case before it rises up naturally to the higher mounted rear fan.

Thanks. I have a question about the voltage curve.

Here is my current curve

How would I go about tweaking this for more efficient temps? I know that mid 70s is safe, but I like keeping my card as cool as possible before going about cable management.

Yeah it's for mhz. That's what I was asking; if it's possible to undervolt the card at a certain voltage (I think it hits 1.062v @ 2050mhz) as to have less total voltage, thus lower temps.

I actually lowered my +80 voltage back to +0, but that doesn't make a difference it seems. The new peak mhz (2050 - 80 = 1970) corresponds with the voltage that was linked to 2050mhz.

I'll try tweaking my memory next (it's at +575mhz or 5580mhz) and see how much I can lower it to see a difference in temps but no difference in performance
