i know i have poor airflow, i was wondering what should i really do?

Have 2 intakes 140mm(come with the case), one rear 120mm intake(very poor quality fan), one Noctua SF12 side panel exhaust and thats it....

Also use a NHD14 on my CPU, no problems at all there... 6700 4.8 Ghz on 1.430v all good thumb.gif

2 intake fans at the front + 1 intake from the side, 1 exhaust fan rear + exhaust fan top. Also have your cpu cooler blowing towards the rear, see if that helps.

Bot and front intake on 100% try to configure the side intake how it works the best. For me keeping it at 60% is giving me best temps, instead of 100% which seems to increase them with 2-3 degree. Also i have my rear as intake because of my H80i so the 2 of my top fans take care of the hot air (specially the one on the middle top) If you have space in the front top of the case for a exaust it will be perfect, just try it and you will see, then you can give me rep for sharing this unusual setup smile.gif

Making a wind tunnel in the case can only do so much for the gpu temps.

As johnd0e mentioned, watercooling would guarantee better temps.
If you can't/don't want to go custom loop, then AIO gpu kits could help to reduce your gpu temps. to a decent level.

Yeah, AIOs work nice on cooling GPUs for cheap. thumb.gif Only have one on my little 960, but at least it not cooking at 70C but 40C now. Just have to be mindful that it don't cool the VRMs, but if you have a mid plate. You can easily leave that on then smack a G10 bracket with an AIO. That way the fan can blow onto the plate to cool the VRMs.

You absolutely should change that rear intake to exhaust. I know you said you have an h80 on it cooling your cpu but honestly you'll lose maybe a couple degrees on the cpu but I think you'll be better off overall if that rear were exhaust.

Hello guys! I think i just damage a 980 Ti G1 Gaming rolleyes.gif

Have two of them, bought a Kraken G10 and a Corsair H55 for the first one, since it has much higher temp then the below card. All good.
Begin the installation, carefully watch one thousand videos of how should i do, seems to be an easy installation. And it was. I was also convinced that i could keep my G1 blackplate while install the Kraken.

Enter on The Witcher 3, 4K with Reshade for test temps. Temps of that game are usually much higher then any other game, would be a good ''stress'' test.

Temps are ok with my usual overclock. Before, with that same overclock on air, temps reach the max limit easily on a hot day and the throttling was inevitable. Was happy. After a while i started to see some weird glitches... not like those black/red boxes when you push too much on Memory Clock, or artifacts like red/white dots/stripes when you push the Core Clock too much... No... it was like... textures glitches? never saw that in my life doing overclock...
Shadows in game sometimes "blink"? A window on a house blink two times all white then the texture got back after few seconds...
I exit the game trying to see a helpful video before work and got BSOD...


Tought that was really weird. Come back from work, enter in game again to see temps and if i would get BSOD again or something like before. Texture on the floor, right next to my horse, keep glitching after a few minutes in game, was looking at it that trying to figure out what was happening...
looking at my temps, CPU TEMP 65ºC(i7 6700 4.8 Ghz), GPU 1 TEMP: 62ºC, GPU 2 TEMP: 65ºC... all good, what should be?

Then after 5 min or so my PC goes down. Just turned off completely. I was like: omg, not my PSU please... it´s a brand new XFX 850W Core
Tried to turn my PC on again, no boot, no signal on my monitor. Take off the HDMI cable from the first GPU, put on the second one, no signal... i remove the power cable for 20 secs, still no luck.

Remove the battery from the motherboard for 5 minutes.
Boot started, then after my BIOS image from MSI(i have a MSI Z170A Krait Gaming last bios update), when Windows 10 logo shows up i saw a blue line on the top of the screen, then two blue lines next to each other, then three... then suddenly i saw all my monitor covered with white stripes everywhere. Then the login screen came and it´s all normal, but, my PC doesn´t recognize that i have a graphics card, not even the second one. My resolution is, also, on 1024x768.

Take the GPU off, begin again the installation paying extra attention to what i was doing, clean all up, apply again the thermal paste again(Cool Laboratory PRO, no, i did not exaggerated, nothing was touching the PCB, everything good and well spread when i remove the H55). Connected again and exactly same problem. Blue Striped, one, two three, then all white stripes everywhere. Login screen all normal. No graphics card.

Removed again the GPU and put the second one on the first PCI-E connector. All good. Played GTA V for hours, no problem at all.

I don´t think i can RMA that card since i opened, it is still in warranty tough. Should i try to bake the card? tongue.gif

EDIT: Oh yea, forgot to tell about my overclock. Nothing special, really. Default voltage, Power target at 109%(max 139%). FAN 100% all the time both GPUs.

When you installed the G10 did you check to ensure the fan was spinning correctly? Also remember that the fan speed curve needs to be manually adjusted since the core temp is much lower. Sounds to me that the memory or vrm got way too hot. You can still RMA possibly. Clean of the collaboratory and put the stock cooler back on before you try obviously. It will also give you the chance to bring the card back to stock and try to see if it works.

I have an asus gtx 980 ti strix that i want to bios mod to get higher clocks. i'm using the Maxwell bios tweaker. I got 350watts total pull but the third down and power table which is the pcie slot is a little odd. it is reading 175000 (175watts) Is that not well over the 75watts it can pull? Would that not damage the motherboard?

hello, just like to post my findings, i flashed the first bios mod on a reference pcb 980ti

i have it clocked at a boost of 1508mhz with an extra 1ghz on the ram making 8gbps.

the settings i have are +70mv and 121% power limit, an extra 280mhz on the corte and +500 on the memory.

i have the link option and prioritized power limit over temp limit.

i have a xspc razor waterblock and backplate with mx2 thermal compound and temps wont go over 45c peak.

i also have it hooked up to an i5 4590(to be changed) with the xspc pro waterblock which is linked to a 360mm rad and 240mm rad, using the corsair carbide 540 case.

as far as im aware, this easily surpases a gtx 1080 which is also overclocked.

Shouldn't be pulling any more than 82 (82000) from the PCIe slot. Who did your bios file?
