Either phone PCS,or personally I would phone DPD directly to clear things up.
Big difference between Crossfired temps.

Thanks, I have already notified PCS by email as I did have concerns regarding DPD having the right address but I will phone PCS up again in the morning as adviced by Mustapha of PCS if the collection did not take place, and now You.
I just find the whole scenario not pleasantly funny as I had barely come of the phone to PCS after being informed the driver had apparently reported being en-route only to receive the SMS saying they had visited and I was unavailable.

I do hope you have been able to sort out your repaste, if not the first check should be to check see if the gpu die is coated with the TIM.
If you apply too much and it is uneven you might end up trapping air in there and not get the benefit of the TIM, if not too much then it would more likely then be a case of not making a proper even contact/sandwich between the Heatsink and the gpu die, might be a good idea to apply the thinest layer on both surfaces while using a straight edged piece of card like a credit card or the likes at about a 45 degree angle to ensure the surfaces are as smooth as possible - rather than relying on the tightening procedure to do the spreading - you only want a very thin layer and you might also want to try applying a bit of firm pressure initially to ensure both surfaces meet flush before starting to tighten.
Proper tightening procedure should be like tightening a car wheel back on, in the form of an X, ie 4,2,3,1.=, do not tighten the individual screws fully, it should be a gradual process, just a turn and a half or 2 a time and then move on to the next, try and use a torch light to visually check that the surfaces are even.
Edit:-*** By the way, do not over tighten, that might just upset things, getting the screws just about thumb tight should be more than enough*** EndEdit
While I do not know what TIM you are making use of Arctic Silver 5 and GELID GC Extreme appear to be the ones favoured by most folk, IC Diamond 7 is said to permanently adversely alter the surface by polishing it.
Isopropyl 99% Alc is about the best cleaning fluid - once you take off the heatsink, even after a fresh repaste it would be best to clean it all up and start over if only to avoid having trapped air within the paste which occurs when you pull apart the heatsink from the GPU die.
Actually, Here are a few threads worth reading that really do a much better job of applying the paste than I attempt to describe:-

[Under perfect conditions the contact surfaces between the processor and cooler would be perfectly flat and not contain any microscopic pits, which would allow direct contact without the need for Thermal Interface Material]

Just a note I've had a few items delivered recently which I missed (and they were subsequently left with a neighbour) and no card was left, fortunately my neighbours are all canny and didn't try to keep my stuff
. Maybe I didn't get a card because they left it with a neighbour but I would think its just as important to leave a card in that scenario.Either way just an idea, I would get in touch with DPD or ask PCS to get in touch with DPD on your behalf to ensure they have the correct address prior to you waiting in for them "not" to show up

Hi All,
I've a Vortex Elite III on the way with dual 7970s, so thought I'd ask customer support about the above mentioned issues. The reply was;
'We've had a few like this so we apply MX-4 thermal compound and cross test these now to make sure it doesn't get this high.'
Which is exactly what I wanted to hear. Hopefully this proves useful for someone.

Well, it had slipped my mind that the initial delivery driver from DPD had indeed called me when attempting delivery as he had realised that his GPS unit had lead him to the wrong location.
Presumably, those that attempted collection had had the same problem but did not know to phone me up and thereby locate me, hence not leaving a card.
Vanthus's comments made me think back and I was able to advice PCS accordingly and they in turn provided DPD with proper directions. The system was eventually collected and has actually arrived with PCS, so that is that part dealt with.
Definitely a good idea to contact PCS by phone when any issues arise.

I have the same arriving and you have put my mind at ease with what they told you
Bumping an older thread but I also had issue with GPU 2 temp running quite a bit hotter than GPU 1. Under heavy load the difference was in the region of 20 deg C. This is with dual GTX 680M.
GPU 2 would often sit at 92oC with the fan constantly switching to full speed to bring it down, with GPU 1 in the low to mid 70's. Now on opening the laptop up you can see why there would be a temp difference straight away, GPU 2 sits further back in the laptop and the cooling fan also has to deal with a heatsink from the CPU. So it's never going to be as efficient as GPU 1. GPU 2 often runs at a slightly higher load also.
I did repaste both GPU's however and noticed that they both had the standard factory thermal paste (more like a putty actually). I had paid for the artic compound extra so was a bit surprised. Checked CPU and it did have what appeard to be Arctic compound. I ordered the laptop on the 10th of Jan, so round about the time this thread was running it's course with people saying the Artic compund option was applied to CPU and GPU. Well not on mine anyway, thats for certain. Perhaps they just started doing it after mine was shipped, seems strange anyway. Perhaps the GPU's are already fitted to the chassis and are not touched by PC Specialist.
So with everything repasted I still have a temp difference (down to about 15 deg now) but both GPU's are running around 10-14 deg C cooler, GPU 2 is no longer constantly bringing the fan to full speed at 92 deg C but is now around the 80 mark at full load. GPU 1 is down to 65 deg at full load. It did take two attempts to get the copper plate to 'seat' correctly on GPU 2. I noticed when i first took it of that the pressure seemed to be uneven, my first attempt was much the same, almost half the chip had no compound spread (and GPU temps were jumping all over the place). Very carefully bending the tabs which hold the plate down meant more pressure could be applied when tightening the screws, next boot up temps were much better.
Now i'm pretty sure the laptop would have been fine as it was, I mean it was bringing the temp down from 92 pretty easily when the fan kicked in to full speed but it was constantly switching speed and was a tad annoying, but there was no danger in my mind of it overheating. I'm just surprised that the optional extra thermal compound was not applied to the GPU's. Im much happier with the temps as they are now and also the steady fan speed at full load.
Laptop is a beast anyway, very happy with overall.
