AXPs in SLI on 2x GTX 480 Heat Issue - Page 4

post #31 of 41
If by anyway you can instal the axp and the stock heatsink cooler plate, your upper card may run colder. why? At the lower card, cold air is intake by the axp, cools the heat from gpu and hot air blows on the vrm heatsink and pcb, this makes that the air inhaled from the upper card is to hot and so on the upper card runs hotter. I am going to mod my lower card today to test if this can work.

So i finish to mod my 2 gtx 570 hd to use the stock heatsink cooling plate with the AXP cooler. I am very happy with the work, the cards look more robust, temps got down a litle and it also takes more time to reach high temps. I will try to post some pictures later.

That's a great mod, looking forward to seeing some photos.
IMO, this eliminates the only weak link in the AXP, as they are otherwise excellent coolers.

I was able to drop the temp. spread between mine from 10C at load to about 4C by fitting four 120mm fans blowing on them on the stock HAF 932 door panel.

I had a 690IIA before I got the HAF 932, but the cards wouldn't fit with the triple-slot coolers, thus the HAF purchase.
Do you have a side fan on your 690IIA? I ask because I bought the optional vented window panel for my 690IIA and fitted a 120mm fan on the door to cool the one 480 that I used at that time. Some side airflow can be quite effective.

I do...

i have 2 140mm fans...

i am also modding the standard VRM/RAM sink as i speak to you now..

i hope to have that done sometime soon and with some new AS5 paste to see what the difference is...

That's a good fan setup you have on the 690II, mine would only take one 120mm on the windowed door panel I bought for it.
I liked that case, got it for a good price and I thought it looked good compared to some other designs.

Ah, you're going to fit the stock vrm/ram sink to the card with the AXP.
That's great, I've mentioned that with a proper-fitting vrm/ram sink plate I may have bought AXP's again instead of the Zalman's.

I've always been leery of using AS5 on a video card, due to it being capacitive, but I guess if you're careful with it........
I used to use it all the time on any builds I did, but just on the cpu.
Been happy with AC's MX series pastes in the last few years though.

Looking forward to seeing how that works out.

Definitely looking forward to seeing those pictures Knivo, I'd be interested in doing that mod as well.

Btw, backing up the MX paste, I used MX-4 on one of my AXPs and it cools just as well as the stuff that comes pre-applied to the AXP.

Also, thanks for the suggestion clerick, but it would just be too much of a hassle at this point. I already purchased the fans for my side panel and have invested a lot of time and labor into the AXPs. Plus, cosmetically I really do not like that cooler =/. But a good suggestion, nonetheless.


CM couldn't get me that side panel, and I cannot find it anywhere. I'm going to have to go with getting a couple of 120mm holes cut into a pure glass side panel, but I haven't had any time to find a local company to do it for me, I have been extremely busy at work. Still debating whether I want to go with 4 fans or 2, just because of price. We'll see.

ok... my dremmel broke so i couldn't mod the standard VRM/VRAM sinks to work today...

but i have now got AS5 on the cards for the main GPU...

The temps have gone down from 74 on the top and 70 on the bottom to...

65 Deg C on the top and 59 Deg C on the bottom card..

A HUGE improvement over the standard TIM on the AXP coolers

I'm impressed!
That's a far bigger drop then I would have expected. I've been considering re-doing my tim with something else, as I just used the stock Zalman paste,
now it may be well worthwhile.

Sorry to hear about the side panel. I have to say that I like the idea of using real glass, it is so much more durable for cleaning than the plastic used on most stock panels these days.
I think AC uses one of their MX series of pastes on the AXP.
