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 :blink: )

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.....

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

      RB25DE NEO with Haltech ECU

      I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
