285gtx

[boiracer]

hi guys quick question, ive recently OC'ed my comp but havent touched the Vid card, its a 285 nvidia GTX, and ive noticed the temps get pretty dam hot, and slowly climbs the longer i play. also read that they do get pretty hot, but have noticed some slowdown once it gets over 70 degrees core temp.

ive noticed that the fan doesnt seem to change speed, should this be an auto thing as standard?

so what ive done is installed riva tuner (which ive found doesnt work with the new drivers properly yet )

even adjusting the low and high temps etc in riva doesnt change it, if i do a GPU test on it, the temp goes nuts and the fan doesnt speed up.........using riva manually atm. when i play games i set it to 70-80% fan speed and it keeps the card at a nice even temp with any game. (bout 60 degrees)

any ideas what to do? ive tryed speedfan and Riva, neither regulate the fan

285's get to around 80 degrees on full song from memory which is ok, thats where they sit with the stock cooler

What's your case airflor like? That could be another issue to look at at it does help to have some other air flowing over the card

thnx for the reply,

yeah so ive read, with the 80 degrees, and putting it thru an uber bench test it hits about 80, but when gaming those temps tend to slow it down....just wondering why the fan doesnt do more earlier, seems wierd to me.

airflow is fine, 3 x 120mm filtered fans with nothing to drag the hot air from near the card, if anything the card working hard ups the temp of the CPU a little, but not alot.

PSU is low mount, but in its own compartment, with a fan front and back.

cool, ill stick to leaving it on auto unless i do some uber gaming, othert than that ive found to run it at about 70% fan speed keeps it nice at around 65 degrees playing crysis full detail.

You could always look at upgrading the case fans - just because it has some doesn't mean they are doing a good job

I swapped mine out for some Coolermaster ones that move a LOT more air than the standard ones.

I also have some Zalman fan's there that move more air than the coolermaster's for the same level of noise so i might change yet again.

They are all hooked upto a fan controller so when doing nothing, just whiz them down and its almost dead silent

speak to your supplier?

Also i would expect the fans to sound a bit more noisy at 80degrees, my card (not a 285) when it hits about 70 - 75 turns its fans on higher automatically but it can take a while for it to kick in for when the fans turn on.

In regards to Riva, yes the most recent drivers brought out by NVIDIA arent usable in Riva Tuner, i just discussed this recently in the PC setup thread.

Long story short i uninstalled the new drivers, found an older driver and now Riva tuner is working sweet. Provided there is a driver approx 3 - 4 months ago for the 285 roll back your driver and then play again with Riva Tuner.

Hope that helps.....

unless you are having specific problems, or play a game that the driver gives better performance for...

you don't really need to update.

[PrayingDeviously]

I wouldve been sol, I thought speedfan would do it.

[boiracer]

yeah riva is doing it now, i updated cause the latest patch of wow was having issues with the old drivers, runs alot better now.

but silly me didnt reboot the comp after playing with fan speed controllers etc, which it clearly said i should do for changes to take effect, lol.

otherwise yeah, ive got room for another 2 fans in the case, and have been thinking of upgrading them, buit its really only the video card that gets hot, the rest is a E8500 3.16 OCed to 4.19gig, and it runs good temp wise, only gets hot if i give it a good hiding for an hour or more on OCCT, or prime.

so ive figured out now that at 66% duty cycle the vid card sits nicely at 65 degrees while playing WoW (alot of peeps say cause its old you dont need much to run wow, but thats crap if you want full detail and shadows it chews the comp as much as crysis, and played for up to 8 hrs straight) or crysis, so ive got some room to OC the vid card too YAY

thanks again for your replies guys
