Problem with new GPU cooler.

Dominor · 26 Mar 2009 at 08:13

I recently bought theAkasa AK-VC03-BLUV Vortexx NEO VGA Cooler on a HD 4870 1GB and since I am getting extremely high temps and artifacts appearing very quickly, to be honest the instructions were simple but I think it may have left out some important stuff. My question is, after I apply the thermal compound and reattach the fan how long do I leave the compound to dry? Since last night (maybe around 9 hours) it has dropped and I am not getting artifacts but the GPU is still very high, going up to 91c on idle :eek:

, should I leave it for a bit longer to dry? Ordered some arctic silver just incase to. Thanks for any help, still new to comp over clocking and heating to be honest.

Hi Dominor

You don't leave the thermal compound to dry, you may have to reseat the cooler but wait untill you get the arctic silver first.
Are you sure the fan is running and if it is can you not alter the speed.

Aha! Think I fixed it, removed the fan into the Odin Gigabyte PSU (Has dedicated SYS fan control) and switched to straight into the mobo and removed smart control, GPU temp is now idling at 34c with fan adjustment yet

, 10 lower than stock, sorry for the quick panic hehe. Damn spent £20 on thermal suppplys XD

Thanks a lot for the help mate

Glad you got it sorted.

It can be a worry when things don't work straight away, lol.

If you have only just ordered the stuff, phone them up and cancel the order.

Nah its alright, I sorta cemented that paste on anyway

so I will probabloy reapply the new stuff better tomorrow, + the new coolant looks pretty good so it will come in handy

It would be worth keeping an eye on your VRM temps as well as the GPU as most after-market coolers seem to lack a bit in that side of things. Use GPU-Z to check them (they are the 3 VDDC temps at the bottom of the Sensors tab) Max rated to 127 degrees! I had to put some extra case cooling to get a side fan blowing onto the back of the card to help keep them chilled!

Around 60c right now, thanks for the tip!

60 is pretty good, you should be fine with that.

Is that at idle or under load ?

Mine idle at 45c but under load hit 85c. - Until I added a fan to blow air onto 'em they were running , under load, at 103c+ :eek:

61 at idle I think, was like that before the fan change though.

Just wondering if I could ask another question, I was taking a good look at my GPU Z after I used the ATI tool to auto over clock the card, and under 95% load my GPU went to 65c which I think was great considering I got almost an extra 80Mhz out of the core, but the MEMIO read at 90c under load. Does that look a little high to you? The card is running fine over clocked but I dunno, 90c sound hot, but is it to hot?

FaceplantSi · 26 Mar 2009 at 14:32

I would suggest that you need to check that your cooler is seated correctly as the MEMIO is located in one corner of the GPU, so if you have proper contact, Shadercore, Dispio and Memio should only be a few degrees apart.

Ok, I will check it tomorrow when I get the new thermal paste and report back.

Dominor · 26 Mar 2009 at 18:18

Was playing Crysis after a quick graphics card boost (overclcocked by just a few Mhz), started to artifact, added a side cooler to my Antec 900.2 to try and cool the card = wouldnt work. Tryed lowering the clock back = wouldnt work. Ordered the XfX version on my mums card and its coming on Saturday. Sapphire is being returned to ****.com, second one I have had to return :O. Probably still gonna try the thermal paste tomorrow morning and see if it helps but daym, better safe than sorry, Tired of graphics cards tbh, but I mean, overheating even with a custom cooler (old cooler is even hotter, tryed testing it back to)? Something gotta be wrong there.

FaceplantSi · 27 Mar 2009 at 07:04

Good luck with that XFX card when you get it. I've heard good things about them and I'm sure you'll have a better card with some VRM sensors too!

I hope you get it sorted cause Crysis is awesome with a good card.

What resolution do you game at?

Dominor · 27 Mar 2009 at 15:26

Was running it at 1680x1050, looked awesome to at a nice FPS, DX10 with Natural Mod, but the new card is coming tomorrow so nevermind
