Raven 2 craziness

I just bought a RAven2 CAse myself from Tottenham Court Road.

Ruined my entire weekend as i transferred everything from my current case into my raven and my PC stopped working. 3 LED lights started flashing on my 4870.

Had to pay a small fortune to get it fixed. I'm getting it back this afternoon as well... Not even sure what the problem is too.


But the case should be very cool though. 3 fans 2 HUGE ones at the bottom as well.
 
ok so here is some pics of the case with the card fitted



Now here is a shot of the case standing as it should be , and a shot of the crazy tempretures at load ( note this would rocket higher if I let them )

As you can see there is something crazy happening here.

Some things I have done

1 . refitted the gpu cooler ( inc thermal grease )
2. tried supporting the card when in the vertical ( note the little plastic doobry in the photo's )
added some small bolts to the motherbaord retainers that hold it to the case , This raised the board a little so the graphics card would bot to the chassis correctly

4. tested alll fans and air flow , no difference 9 certin this is not the problem anyway the results are too extreme.

So none of this works , I am pulling my hair out , I am thinking it must be weight , pulling motherboard twisting or something , but its just plain crazy tbh

Any help would be greatly appreciated

when you have the case upright as it should be are you certain the urethane foam wrapping you have it sitting on isn't being sucked into or restricting the fan intakes?

for sure , i have removed it , I have also tested with and without case fans on with same result.

Someone suggested that the heat pipes on the GPU may now be working to trap heat ob the card .

perhpas this is so , but to get a jump from 60 to 120 seems excessive
 
Direction of mavity actually has some effect to heat pipes.

While pressure of expanding/vaporising liquid would keep some flow that heat would still probably try to go upwards so if most of heat pipes are below level of GPUs heat might not get moved away evenly to whole heatsinks while condensed liquid could also have to fight longer way against mavity.
 
Ive got a raven2 and cooling has been great - tried with 5870 and 5770 (crossfired), also a friends 4870 for a brief time. GPU temps on all those cards seem to run at the low end of what anyone has reported in other cases.

As EsaT mentions it could be a problem with the heatpipes - but even half-decent heatpipes normally use a wicking material within the pipe so that capillary action returns the liquid to the evaporator - with mavity having only minimal effects. This allows decent CPU coolers to post good cooling flat on a bench and within a case on their side or even upside down.
However IF your GPU cooler uses cheapo heatpipes with poor or no wick material (maybe just grooved pipes) then that could result in very poor performance.
Having looked at a picture of that cooler it certainly looks like this could be the problem as in the raven the pipes will be vertical, but on a bench or in a normal case they will be horizontal.

I suggest emailing the manufacturer of the heatsink and ask them if running it at a vertical orientation should have such an impact on performance.

yes ,

it would seem the cooler is the problem , I removed it and put the stock cooler back, its in the 90's on load now , which is pretty normal for the 4870x2.

Guess its word to the wise for those looking at this case and certain cooling options.

I am pretty gutted though , I love the case and the accellero xtreme was a fantastic and quiet cooler , it took the heat down to 35 c at load in some cases , and was infinetly quiter then the stock cooler.

its certainly not a poor or cheap cooler , I think as stated earlier its a design constraint.

So now I am at a loss at what to do , might sell the card and cooler, and get a quieter card , they still fetch a decent price .

I actually read that this card and cooler where fine on BJORN3d , ahh well .

thanks all for the advice
 
Damn, that sucks.

Couple of things you could check, you probably already have though :(

Check the 180mm fans are actually spinning properly and what speed they are running at. One of mine didnt like being plugged into a motherboard header - it was spinning far too slowly so in the end I just used the supplied 3fans to 1molex adaptor that came with the case.

Also if i set the fan under the gfx cards to high it drops their temps by about 5 to 8 degrees - means they dont spin up their fans so much (using auto profile) and whole system becomes noticeably quieter when gaming -worth switching all fans to high to see if it makes a difference.

Check the airflow to the fans isnt blocked - maybe vents at bottom didnt have metal pushed out of cutouts properly when made? try removing fan filters?

Does the card with stock cooler also cool more with case on it side? With window on or off?

You could also email silverstone see if they have any suggestions.

unfortunately this has killed my card.

I think the damage was done with the accellero extreme , and re-fitting the stock cooler was simply delaying the impending death cased by the overheating of the accellero .

Looking at the cooler design , it does indeed use pipes that flow to large cooling block / fins at the back of the card.

Word to the wise if you buy and use this case with a 4870x2 do not use the accellero or potentially heat pipe based coolers that may be effected by the vertical position

Now sadly I have to attempt to RMA the card with XFX ,its only 6 months old , but I hear they are a nightmare to deal with.
:mad:
 
Do you still have a warranty after putting an aftermarket cooler on?

I'm getting a Raven 2 for Christmas, hopefully I don't have the same issues, although I only have a single 4870.

Don't even bother, XFX don't do RMA's with customers you have to do the RMA through the retailer you bought it from.
 
Had to RMA my 4870X2 to Ocuk who confirmed it was faulty and sent it back to XFX, 4 Weeks later got a full refund.
