Here is my dillema. I have shuttle sg45h7. Here are the cards i'm looking at.

newegg.com

My question is I like the rev 1 cooler because it exhuasts out the rear keeping some heat out of the pc. I know the rev 2 cooler is cools better. Is this really going to be an issue with the 5770 and the shuttle?
Is the sapphire vapor x cooler better on these cards and worth the extra money?

I got rid of my asus 4870 dark knight because it was way to hot inside my shuttle.
Thanks for your advise.

I also have an SG45H7.

I had the 5770 v1 by ASUS.. it was okay, but ran loud. I replaced it with a 5850 by Sapphire which runs much quieter and about as cool, if not cooler (runs on much lower voltage than the 5770 did).

I would not advise the v2 cooler or Vapor-X with the SG45H7. The inside of the case gets rather hot and I find cooling performance optimal when the GPU deals with its own air.
 
There's this 5770 with a different Vapor-X cooler: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102873

It seems new because I haven't heard about this one yet. Second revision perhaps of the Vapor-X 5770? Oddly enough, it isn't on Sapphire's website: http://www.sapphiretech.com/presentation/product/?cid=1&psn=000101&gid=3&sgid=643
Compared to the first version, this one has a thick copper heatpipe protruding from the base of the heatsink into the fins at the top.

Also, it comes with a $10 mail-in rebate. I'm planning to get this one this Friday seeing that my current Radeon HD3870 is randomly spazzing out and resetting itself. ~_~

Thanks for the info. I may just get a 5850 to keep things quiet. I don't really need it but I don't want to get the 5770 v1 if it is going to be loud. My sg45h7 is almost dead silent right now.

Thanks for the info. so my question is how much heat is the v2 5770 going to dump into my case?

Right now I am using the crappy onboard intel graphics. My idle temps are roughly 40C and full load is 65Cish.

That completely depends on the airflow in your case.

@octoberasian: I think that's another revision. I don't think that's vapor X.

Mine too. It gets more silent if you replace the noisy NB fan -- I replaced it with a Zalman NB-F47. I found the NB fan one of the noisiest default parts since it is so small and spins at almost 5k RPM to produce a high-pitched squeal. I had to mod the mounting mechanism to get it to fit properly.

The 5770 is really unreasonably loud without good ambient temps IMHO. The SG45H7 only has that one 92mm fan both cooling the CPU and exhausting hot air, so ambient temps are pretty bad. End result is the small fan spins at high RPMs and really squeals. The 5850 fan is big and pushes a lot of air, staying at around 21-22% and dead silent. It gets up to about 25% while gaming. I found undervolting it to 1.00v really pushed down the temps as well. I couldn't undervolt the 5770 far enough to keep the noise/temps under control.

I've been wondering about that as well. I've read around that there have been stability issues with the first Vapor-X model, supposedly. That or the card's Vapor-X cooler didn't perform as well as the Version 2 of the stock cooler, or it's much noisier than the Version 2 stock cooler.
 
So does anyone know how the heat output compares to the 4870. I couldnt use the 4870 in my shuttle because it dumped way to much heat into it.

I have noticed lately that the northbridge fan starts rattling but then quiets down. Soon I will need to replace it. I tried just unplugging the fan but the heatsink got very hot. Do you notice that with the zalman.

The Zalman is quite effective -- it gets hot but it's doing the job right. It's at least as good as the stock heatsink/fan combo, minus the fan and minus the noise. But it really is a PITA to mount since the included mounting hardware of the Zalman doesn't work with the loop orientation of the SG45H7 motherboard. Thermal epoxy could make it easy.

I have been eyeing this cooler for a while just haven't ordered it yet.

Oh that makes sense. Your OP mentioned a 5870 Dark Knight which Asus never made. All of the 5770 and 5850 revisions are much cooler than that 4870, and contribute much less to ambient temps. I was pretty comfortable with a PNY GTS 250 1GB that exhausted air into the case, and that runs hotter than the 5770s and 5850s as well. In hindsight you may be able to make the 5770 v2 work. I wouldn't recommend the v1 for the noise, and the v2 is much quieter.

The SilenX was my second choice. I didn't want a small fan though. Looks like the mounting hardware of the SilenX will fit the SG45H7's loops fine.

Fixed my error. I don't want to get the v2 5770 and not be happy with the temps and not be able to return for a refund. Guess I could go with a sapphire or other brand since they allow for a refund but I like the fact that xfx has a lifetime warranty. I have a decision to make now.
 
I'd go with the v2 by Sapphire or ASUS, failing a 5850 that is (if your budget allows, as it will be a huge upgrade to the 4870 where the 5770 will not be). XFX has been known to cut corners.

This post at OCN from the topic you linked is interesting:

Basically people might have been jumping to conclusions too soon that it was XFX using a custom PCB. Looks like it was a revised ATI PCB if several of the AIBs have that PCB layout. Does not excuse XFX from their 4890 fiasco, but reassures 5770s buyers a bit.

Noted, but I'm skeptical unless Sapphire and Diamond jump on board. Those two are sticklers for AMD reference designs, and the newest Sapphire in this thread still uses the classic PCB as evidenced by the two XFire points.

Plus the boards are not exactly the same. They're even less "reference AMD" than the v2 egg coolers, which were hardly reference. Looks like AIBs are just jumping aboard the cost-cutting train to me.
