Is 97°C and 88°C too high for crossfire 4890. - Page 2

Well, thanks so much for your responses guys, you don't know how much I actually appreciate them.

M0E, In CCC, I didn't see "application controlled" as an option for V-sync. I only saw a bar with "Performence" to the left and "Quality" to the right in the "3d" tab.

I'm running the newest 10.12 drivers, so if you state to switch drivers, I'm assuming you mean to roll back to old drivers? Which doesn't seem logical to me but I'm willing to try options.

brettjv, your right. Well, I keep thinking that vsync ON seems to cap my frames at 60, but vsync off made it around, lets say 100 for Battlefield BC2.

So to me, scientifically, it just seems like the GPU has to work harder and is going to get hotter with v-sync off, even though most of you guys said it wouldnt make a difference, but isn't 40-50 frames + a significant different for workload on a GPU?

And how difficult is it to remove the heatsink on a GPU? I've overclocked my CPU and re-applied thermal paste with a 3rd party cooler, but never messed with GPU's because I heard they are uber cumbersome.

I can always up the fan in the ATI CCC.

Thanks for all help, I'm going to try everything that was stated.

Oh, and my case ventilation seems good? I have (4) 120mm fans there seem good quality, and (2) 140mm fans on top.

Does it matter if I daisy chained them together? Imean, will these make them weaker in power and reduce their RPM, as opposed to plugging each one individually into a 4pin molex?

Thanks again.

Ok, played World of Warcraft for approximately 5 hours (heh I know...),

temps hovered consistently in the 80's Celcius at 100% GPU load.

As soon as I tabbed + alt to my desktop to see GPU-Z and HWmonitor temps. recordings, the temps dropped to about 70's Celcius.

The MAX that one card hit was 91Celcius, and the max for the other card looked was 86Celcius.

I was getting about 100-200FPS and at max 230FPS in ULTRA HIGH graphics, 1920x1080 resolution.....

Besides my cable management, which I'm doing Thursday, not sure what else to do. Even the single 4890 ran hot (High 80's 100% load).

I research via goggle and it seems these cards just run hot. I see people listing certain temps of 50's being safe and that seems ridiculous to me, since I have good cable management and great airflow, and I have seen this card runs hot with just 1 card, let alone 2.

Anyway, the max being 105Celcious seems more understandable to me. Why don't they just list it on the website??? I hate guessing at this stuff... I don't get any crashes or BSoD, actually, never have.

If anyone can recommend super strong case cans I can mod mine with, that be cool. Besides cables management, I'm going to move the second (bottom) card to the top slot and see if that helps. Cards are pretty clean as is though, used duster a few weeks ago.

Should the power supply with fan be facing upward or downward? I DO have a grill on the bottom of my case for air to get through...Wasn't sure if the other setup my change temps (i have the fan facing down on the PSU right now)

enough rabbling, thanks for your help.

It shouldn't be hard at all to remove the heatsink off those cards, in fact it should be easier than handling a CPU cooler since all you have to work with is a small PCB in front of you.

Did you get around to cleaning the heatsink/fan? If there's enough dust in there it can hamper airflow and that'll jack up your temperatures quite a bit.

Yeah, actually I bought this new NZXT case about 2 weeks ago, and used compressed air ( duster) to clean the entire inside.

I'm really meticulous and strive for perfect cable management and a clean case.

So when you guys were advising me to do that, I knew I had already done it, but I was just going to go inside again and do it just to please ya guys

Anyway, I'm going to look into manually setting up fan profiles, either using a program (I think someone suggested RivaTuner?) or using ATI catalyst.

Although, doesn't Catalyst just monitor 1 card? I mean, I know I could turn the fan speed up using Catalyst, but I only see 1 card listed, are they linked or something......

..And do you think adding stronger case fans like Noctua would make a difference? instead of the stock NZXT ones I got? I don't want to spend money if it won't make a diff. in performance.

this would be the point in time where I would prefer to remove the heatsinks... check for flatness and solid contact... lap where it is needed (check with a glass plate) and then apply some mx-3/mx-4.

97* is not quite in the dangerous zone, IMO. 88 is fine. If it were my computer, I would still try doing something about the 97* one for 24/7 use. I am assuming that these two cards are right next to each other, and the hot one is having issues intaking air because the card below it is blocking the airflow. The best thing to do would be to put a fan blowing cold air on the side of the case to try to bring the temperatures a bit more even. Other than that, re-applying thermal paste is always a good idea.

However, in my experience, implementation of v-sync w/ATI cards is pretty frickin' flaky ... having it work one time and not work another time even though nothing has changed was not that uncommon ... neither was having v-sync just not work at all on certain games.

I recommend grabbing D3DOverrider from the Rivatuner installation (you don't need to run RT to run this, as the app is 'stand-alone'). This will allow you to reliably force V-Sync w/every game.

97C is quite hot, yes, but if you have no extra slots/space between cards in x-fire it's not especially shocking for the top card to be that hot in extreme situations (like when v-sync is off/not working, and you're running furmark, or possibly an intense game like Metro or Crysis).

Have you tried setting up a custom fan profile in Afterburner to bump up the fan speeds at a lower temp (vs. auto profile), and increasing your case ventilation?
BTW, I don't know how people can say v-sync doesn't make a difference, because I just tried this and my temps went down like 10 degrees on each card.

The cards are obviously capped at 60FPS now... Which I feel isn't using the power of the two 4890's but whatever.

Funny, I have the graphics on ultra, and it seems to get a bit choppy on this certain "woodlands" area on WoW, and my FPS go to about 50fps. I really thought the 2 4890's would have been enough to overpower it...

strap a 120mm delta fan to the cards. temps will drop by 40C.

The only time v-sync won't help w/temps is if the game is so challenging graphically that the FPS would never be above 60fps. In this case, then the 60fps cap would never come into play, therefore it wouldn't change temps.

V-Sync, in case your unaware, causes your FPS to be capped at your monitor's refresh rate (typically 60Hz). The actual point of the feature is to remove the screen-tearing that often occurs when the FPS is > the monitors refresh rate.

And it so happens that a 60Hz monitor cannot physically display > 60fps, so in reality by having it on, you're really not 'wasting' your card's power at all. You're also not wasting electricity and heating up your card for no actual benefit.

Besides, the real 'power' of your cards does not reside in their ability to run at 100fps (you can't see it anyway due to the monitor) it's in their ability to not drop to very low FPS, making a game unplayable. Which isn't affected by v-sync being on

Also ... online games aren't really the best to use for judging your rigs' graphics prowess ... imho, there's just too many variables involved.

Strap a 120mm fan with some cable ties in between the 2 cards (on top of them i mean), and it will go down alot.
