Yes, as a temporary measure (and to get it all figured out yes absolutely).
But when you have time I'd change it over.
You can get cheap pads at 3 w/mk ish on Ebay for under a 5'er (10cm x 10cm squares) which cut nicely into shape.The key is sticking something slithery on top the pads (thermal grease?).. screwing together then unscrewing to see where the residue is left. (the pads that have really good compression might even STICK to the block when you lift it back up if the contact is absolutely excellent.
But you won't know for sure how good it is; until you fire it up and do some benches and compare temps.
(Also don't worry too much; if you stick to the manual you can't go wrong -- it might just not be as absolutely perfect as it could be).
There's also no harm in adding extra pads so more of the PCB makes contact with some part of the block. (Just be careful you don't compromise contact on other components in the process).
I've got temp probes attached to a cheap 25 bux fan controller like this:
Just some examples for a bit inspiration (don't worry about going as indepth as me)
This is what I done with my 1080 Classified (I added pads that nvidia/evga & EK didn't use for even more surface area heat dissipation)right click & 'open new tab' for full size
You don't need to get into it as much as me, or anywhere as near as much detail.
Sorry don't mean to overwhealm you, I'm just crazy as they come lol. (and obsessed with temps and pushing to the absolute limit)...
But notice in my '2nd last picture' how hot the 3 memory chips are compared to the others? (Purely due to their vicinity to the VRM -- a lot of heat spills over from it. After this mod (and a few other little tricks) on my last card; I could hit a ridiculous +925 on memory :
But just to give you a bit inspiration/food for thought :-)Edited by nrpeyton - 4/27/17 at 9:53pm
