[Official] 7870 Tahiti LE (XT) Owners Club - Page 516

post #5151 of 5244
^This.

I wouldn't worry much about core until around 75C, but the VRM on these suckers? 105C MAX. I think there's some crummy 3-phase regulation here. Remember, this Tahiti is running on a reference Pitcairn board. They just aren't meant to do so much.

Aaaaaand, the post goes to the next page. lol

90° while gaming is a norm for me. The highest I've seen the core go was 97°C before it started throttling itself. That was with a 1200/1600 OC. I have no idea what my VRM temperatures were, but I've since dropped the clocks to 1000/1500 to be safe. Even at these modest clocks though, the VRM on the top card can hit 108°, where it will also throttle the GPU. Should I be worried? Do all the Tahiti LE's run hot?

Its quite a bit faster. I found my 2 7870XTs to be some of the buggiest prices of hardware I have ever owned. it was like driver updates ignored them or something.

They kinda do. That top card seems pretty toasty, especially being the sapphire model. Have you considered replacing the TIM? The stuff may have cured over time, especially with all that heat. Maybe add an exhaust fan next to the cards on the case?

What do you mean, replace the TIM? And I have an intake underneath them, one on the side of the case, and even one if those pci slot coolers sandwiched between them.

The top card almost always suffers from higher temps because it is basically intaking the exhausted heat from the bottom card. The top card is starving for fresh air. You would need a very well placed side intake or front intake to provide that top card with good fresh air.

Changing TIM won't do anything. The tiny heatsink uses a 2mm thick thermal pad. Changing the pad for a very high performing one may gain you 5-10C on VRM if you're lucky. Fujipoly Extreme works very well (11 w/mK).

Is that PCI slot cooler exhausting air out the case or blowing right into the top card? The fans are so close to each other I doubt it's actually helping anything. Side intake helps but the type of fan used matters, directional airflow works better. Your side intake might be spraying air out at a wide angle instead of directed towards the top card.

May I suggest moving one of those top mounted fans near the front of the case, specifically in the top position? It would do a better job of feeding both cards fresh air. Perhaps placing another fan on the side panel as exhaust will help as well. The location of the fan on that panel is directly beside where the vrm is located on that particular card. Doing this on my case netted me a 5C drop on my core, and my vrm temp drop from 105C to the upper 90s. I can't remember the exact amount. It's been a while...

I tried using the side panel fan as an intake, and saw a smaller drop than I got when it was positioned as exhaust. YMMV.

What I would do:

-Move the ceiling fan nearest the rear to the front-top of the case as intake
-Move the fan in the floor to exhaust on the side panel
-Run a loop of Heaven and report results

Seriously, I'd like to see how/if this helps you, or if my results are a fluke!

I drew some circles so you could see all my fans. Blues are intake, reds are exhaust, and the greens are internal fans to assist with cooling the cards.
I'm using all the possible fan mounts on my case.
The pci slot cooler just blows onto the top card.

Brother's Sapphire HD 7870 fans died.

They won't turn on unless fan speed is manually set to 100% or the GPU's internal temperature rises to 80+ (and even then it runs at 100%).

What's the cause of this? Temperature sensor gone to kaputz? And what would you recommend to fix it?

I'm thinking a Corsair H55 + NZXT G10... or one of those Arctic Cooling kits. Is it even worth it for a HD 7870 nowadays? Probably cost well over 120$ CAD to fix it.

There was an issue with the Crimson 15.11 drivers that screwed up fan profiles. Update to 15.12 or 16.1.1 and see if the problem fixes itself.

If not, try using MSI Afterburner to create your own fan profile.
