Hello, I own a HD 7970 GHz edition from Gigabyte, under load this card will hit 78ºC and be extremely loud (can hear it over my headphones while gaming), I have 2 120mm fans as intakes and 1 120mm exhaust on my Phanteks P400, even after multiple repastes with Hydronaut it keeps hitting these temperatures. What can be done to possibly fix this? Any help is greatly appreciated.

With the hot weather settling in and ambient room temperature increasing, those temps are within specs for that card under load, card fans get loud because ramping up speed to cool down card per card default fan curve (or custom through gigabyte card software or Msi afterburner), I have a matrix R9 290x and it runs at same temps under load, I found having 2x 120mm speed adjustable fans at drive cage one above card (cooling card PCB, mobo VRMS and mobo northbridge since using CPU watercooler) and the other underneath the card (cooling Power supply and helping card fans) both re-enforcing front panel intake fans air stream and blowing air horizontally above and underneath graphic card improve dramatically it's cooling under load (especially when you ramp up those fans speeds while gaming), I have all fans attached to asus motherboard and their speed adjustable through Asus Fan Xpert. That would allow you run card fans slower for quieter cooling especially if you make curve less abrupt.

Well I do have a fan curve setup, but it hits 78ºC anyway, I don't have any mounts for intake fans at the bottom, though I could add a fan on the top to see if that will change anything

You can fans by the drive cage, it would re-enforce front intake fans air stream and give you a comfortable cooling headroom with their adjustable speed, I have them one just sitting on bottom of case and the other attached with zip tie to frame) and they do really make a difference. This is not to mention increasing all case fans speed proportionally while gaming to have top and rear exhaust fans working in concert with intake to achieve a nice airflow around graphic card and mobo components.

But I don't even have a drive cage in my intake area, to get 3x120mm would require me to remove the drive cage undernath the midplate in this Phanteks P400

I don't have attachment either lol, I have an old In Win Buc 666 (above picture is corsair vengeance C70), you should have better air flow on graphics without drive cage in between front panel and card, if you already have front panel bottom 2x fans installed try to make their speed adjustable (through motherboard software or through fan controller) and increase it while gaming, keep case side panel open as a last resort solution during long gaming sessions.

Indeed, especially the 7970 known to run a little on the hotter side. Ideally one would like graphic card to run under load between 65 and 75 max to minimize impact on other system components, graphic card internals (VRAM and VRMS) and performance and maximize card life expectancy (debatable) despite being designed to withstand much higher temps (90 to 95C), new high end GPUs have more temps monitoring sensors for more comprehensive card performance and cooling adjustments which on the other hand makes their custom overclocking not as straight forward as the older generation cards.
Are my 7970 temps too high? http://www.tomshardware.com/answers/id-1782982/7970-temps-high.html
