7970/50 Arctic Accelero Users

Just went to cancel the order on my Arctic Cooler to find it has been dispatched

Oh well! I'll leave it on 100% fan speed and hope for the best.

Expect a trust message about your paste Taken. Lets do business.

The 'mighty' Tommy recommends you use Akasa Thermal Tape. One things for sure, it turns a 5-10 hour (minimum install) into a 30-60 (maximum) minute install.

Why do you want my thermal glue? The 10 hour cure time will be alright. Just leave it overnight and all next day at work!

If you sell me your glue ill buy you some thermal tape. The tape is quicker and easier to use, plus the heatsinks have no chance of falling off. I'm sure tommy can confirm this. However im a strange fellow and use the glue, however i need a bit more but can't find any to buy. The only place you can get it is from new Accelero customers, or old ones who didn't use it.

Sadly arctic stopped producing it because it had bad feedback from the community saying that it doesn't stick and provides poor thermal adhesive qualities. I asked Arctic themselves, G1 is no more Taken.

Good thinking tommy.

Trying to decide if its worth taking it apart and moving the CHL8228 voltage regular around so its side on. I only have thermal tape to attach it with. Will that have any effect on the vrm temps? I thought it was linked.

It might, but then again, the tape may negate the effect, if temps are ok, then just leave it be, but I understand the willingness to find out as it gets like an irritating itch.

Is the CHL8228 temp different from the vrm and GDDR5 temp that hwinfo shows then?

I don't know which one is which(vrm 1, vrm 2 in hwinfo.

@TaKeN,

have you tried splitting the pcie power cables, i.e if you have one cable with a 8+6 plugs, use 2 cables instead to split the load on the psu, it worked for a 7970 WF when I had it for a try.

The Extreme is a far superior cooler than any stock solution and got me higher clocks@1200/1800+ instead of 1100/1575'ish(off the top of my head), but it did clock better with added volts on a low Asic.

Yes, the itch is exactly what i get. Its just like having crabs all over again.

If i can get my hands on some more G1 then i think ill have to take it apart and refit it. However i only need to do two of the heatsinks so it won't be a big job. It might only be a few c, but it all adds up. Its actually quite enjoyable all the tweaking, fiddling and building. I hated installing this thing first go, but now its almost like artwork. (especially using the notoriously fiddly G1)

Just need to convince Taken that Akasa tape is the way forward for him.

 

[LtMatt]

I found a datasheet for the 7970 Voltage Regulator CHL8228, is that the same thing as the vrms or is that separate? Because the temp range on this says "+3.3V supply voltage; 0ºC to 85ºC ambient operation". Mind you, that says ambient operation. I get the feeling no one will know the answer to this question.

Careful, you'll end up with Petey syndrome. Fun while it lasts though

Keep your eyes peeled for G1 please Mr Petey. I don't care if you have to ship it in from China.

 

[Uncle Petey]

May be worth seeing if you can get some Alpenfohn thermal glue. Ask them nicely and you never know. Pre-mixed and cures fairly quickly.

But its permanent, i want to keep my warranty in tact should the poop hit the fan. Its either G1 or tape, but seeing as i have it all covered in G1, id rather do the last two heatsinks that way as well.

That's a shame they have stopped doing it.

Also you might want to amend those links in your post.

It's not permanent dude.
I'm aware of the of the one guy that bricked his 7970 when trying to remove the glue and then being told by Alpenfohn that it isn't supposed to be removed. But having used and removed the stuff myself, I can only assume that they've either since changed the formula or the guy tried to rip off the sinks like an angry ape (since he actually broke off one of the VRMs) and Alpenfohn covered their own arses in a pretty poor manner.

Like I said before, it dries like rubber sealant, not cement

So a bit of gentle twisting and it comes off like G1?

Family safe this time.

 

[Uncle Petey]

Yeah, may need a thin blade to help prise it off, but a bit of wiggling and it's done.
One thing I will say is that getting it out of the little nooks and crannies around the VRM's requires a little patience since it's rubbery.

Wasn't for me.

Hmmm, well i can use that as a last resort pete. I'd still prefer G1. Everyone is on G1 watch.

Point noted, link removed. Thanks Mike.

Hope you find some. Did you ask them if they had any old stock of the G1 they could send you? Surely they have some lying around somewhere.

I asked, they said no. I asked for a non permanent alternative, they said search amazon.

lol, surprised they didn't suggest the bay.

 

[LtMatt]

Its like gold dust. But someone, somewhere, reading this thread in a land far far away might just have some.

Trust me that person plox!
