Thanks, that is helpful. I wasn't aware of the vented base panel and will have to look into this.I was planning to use the top and front radiators as intake, and the rear as exhaust (possibly with undervolted 80mm fans), since that is how my current Air 540 case works best, after some experimentation. However, I may try the same configuration as yours to see if that improves temps. I generally prefer not to use 80mm fans, because to be any use they normally have to be...
I'm about to start a Parvum s2.0 build and will be using a 4790k, a Titan X, 2 Alphacool ST30 240s, and - if I can get it to fit - a D5 pump. I'm planning to use Gentle Typhoon 1450s with the radiators and hoping I can undervolt them at 5v. For those watercooling their Parvum cases with a single GPU, I'd be interested to know what speed you are running your fans at and what temperatures you are getting on the CPU and GPU when stressed, particularly in something like BF4...
I have an MSI Gaming 980 which also OCs to about 1480. I also have a Gigabyte 980 which OCs to 1560. When playing BF4 both have a minimum of 100fps and I notice absolutely no difference in gameplay as a result if the 5fps or so difference between the cards. Frankly, I wouldn't waste my time thinking about replacing the MSI card, particularly as it runs so quietly. The chances of getting a card that is stable at 1600mhz is pretty tiny. You're more likely to get around...
I just went from two 780 SCs in SLI to a single 980. I game at 1080p on a 144hz monitor, and need enough gpu power to get well over 100fps in BF4 consistently. With the single 980 running at 1529 Mhz I get very similar framerates to the two 780s. However, it is much smoother, as well as producing less heat. For $80 vs $365 there is no question I would get the 980. And then you have the option of adding another one later if you really need extra power.
Just received my Gigabyte reference 980 today. I ran a quick test of Heaven at 1419 Mhz and it ran perfectly. Dialled it up to 1482, again not a single artifact. Then tried 1529, and still no problems. Thinking this is too good to be true, I played a few hours of BF4 at 1529, waiting for it to crash. It never did. Not even the slightest artifact. I was getting frame rates just a notch below my SLI 780s, but much smoother. In a few weeks I will have this card under water...
If it's coming through your headphones it's probably not coil whine. It's probably just a noisy PC, or possibly a ground loop. I would suggest trying an external USB soundcard - the ASUS Sonar U7 or something similar.
Thanks.
I have a number of fans whose speed I want to reduce. Aside from a fan controller, I understand that speed can be reduced through appropriate cables. As I understand it, there are two ways of doing this. The first is to use molex adapter cables which use the 5v rail from the PSU, or which use the 12v and 5v to produce 7v. The other way is to use a cable with an in-line resistor. From what I have read, using a Molex adapter to produce 5v is safe, since it uses an existing...
If you're running them on air you can expect the top card to hit 80 degrees frequently, and fans from both cards will probably ramp up to 60-100% during gameplay, depending on how hot your room is, how good your case airflow is, how big an overclock you can get and what games you play. I had to liquid cool my 780s to be able to tolerate the noise, otherwise I would only have a single card. But I have a hot room, overclocked cards and I'm a silence freak, and you may be...
Get the second 780 in SLI. A single 780 Ti will only be a small improvement, and probably not noticeable. I have two 780s in SLI and it runs incredibly smoothly, no microstutter or problems at all, and a massive improvement over a single 780 in games like BF4. The only issues with SLI are additional noise and heat, so make sure you have good airflow in your case.
