i once tried to overclock my GTX 660 ti, but when getting my benchmarks before starting the overclock, i noticed that performance drops a lot after about a minute, i can only assume it was because that's about when the cards started reaching higher temperatures.

i live in a pretty hot country, if it was just slightly hotter i could use the back of my PC as a cooling fan for me.

i have stock cooler and i assume it's supposed to be enough for a non-overclocked GPU, so in that case i need a new case or case fan. and i was wondering what's the best solution and how effective it will be.

will the influence be minor and i'm better off with new GPU Cooling?

is there good GPU cooling that i can just take off the GTX 660 TI when i'm done with it and put it on my next card?

will i need a stronger PSU as well?

i should note; i don't wanna mess with water-cooling, too expensive and too complicated from what i hear.

TL;DR: GPU very hot, need know how much effect if install new Case(with good coling),new case Fan, or new GPU cooling

Yes, the best option seems a new case with better airflow. I kinda prefer silent cases like fractal define r4 and nanoxia deep silence 1, but corsair and antec truly make great cases, especially regarding the airflow. Most good mid tower cases today have max vga card size in their specs, and most allow removal of hdd cage for even larger cards. Whatever you get, just make sure that psu goes to the bottom, and that you, at the very least, get 2 fans, one front and one at the back, and that they are both at least 120mm. Top fans are a bonus. Big side fan can possibly obstruct large cpu fans, so check for that. A good case with nice airflow can easily shave off 10, even 15 degrees.

Overclocking your 650Ti with almost any type of cooling won't help much, because this model just craves for high memory overclock... and that's something you can only overclock so much until it becomes unstable - regardless of the cooling you have. VRM cooling is another issue, as some aftermarket coolers don't do this properly. Arctic makes some quite nice coolers, if you absolutely want one, so take a look.

Frankly, I have to say that once your card starts requiring overclocking just to get a few more fps, you are much better off getting a new card. Like GTX760. What PSU are you using, BTW, this might need an upgrade as well (please write the complete model, not just the wattage).

your best bet is a good quality side fan directly on the card. make sure your case has plenty of airflow. are you guessing that temps are the problem? use GPU-Z to monitor your cards performance while trying to overclock? are you increasing voltage when overclocking? are you aiming for a number or bringing the over clock up by 10 at a time

if i get only the arctic cooler will it be enough despite having horrible airflow?
and can i re-use it on my next card?
i don't mind not overclocking it... i'm currently playing skyrim with lots of visual mods and first minute is a smooth 60 fps (capped) and then it's 40 when stationary! if i exit, wait for the Fan to settle down (cus the card is getting cooler) and start it up, same thing all over again.

i got enermax Naxn 600w.



my case has terrible airflow, my room has terrible airflow.
for a side fan i need a new case i think, i'm not sure how this works, any good links on this?
i noticed the issue in skyrim, more info in the reply to herrwizo.
and i noticed a while ago when i was trying to overclock that temperature was an issue.
i'm not currently trying to overclock, i just said that i recall when benchmarking(before the overclock), whenever the card got hot, the performance got bad.

That's normal, hot temps make your GPU throttle to prevent overheating. Since you got a case with bad airflow, hot ambient etc, you would have to replace pretty much the entire setup; get a new case, new fans, optimize airflow, use A/C when possible...

As for the arctic's cooler, you can reuse it on another card but you have to check the compatibility list first. By replacing the cooler, you also void warranty on your card, although that's usually not a concern in cases like yours.

i understand the throttling thing, that's why i'm looking into cooling solutions.

would i really need a new case if i were to buy a good case fan? or vice-verse?
and on that note, what's a good case fan?
every arctic cooler i see is compatible with my future card (gtx 780)

a 9 year old case i think, 1 exhaust fan with no option for more fans.
i think i'll get a case with more fans/option for fans, and see where it goes from there.
how do i check if my GPU/next GPU will fit into the case? or is it not an issue as long as it's a mid-atx case?
do you know any good cases with lots of fans/good cooling? for now i'm looking at antec gx500, lots of fans.
