I'm not quite sure but I wouldn't necessarily expect you to void the warranty of the cooler when you lapp it... Granted they'll probably a notice a difference on the head, they should notice a difference, but I don't think it'd effect the warranty situation.

Next week I'm going to do a complete PC overhaul. Got a new PSU coming in with new sleeving. I'll probably lapp the 620 again just for good measure. Then I might even look and see if its possible to lapp the GPU while its still on the PCB... I'll take a look at that too! Going to reseat everything, make sure the thermal pads for the VRM and memory is all good and have my card ready to overclock it to the max!

I just figured better safe than sorry for at least a few months, I'm sure lapping will drop temps about 5c looking at how rough the surface was (still way better than the 480 heat sinks which one had 1/16" gaps on the heat pipes rolleyes.gif ).

There much of a risk of damaging the gpu chip by lapping it? Guess I never thought about that being to much of a benefit.

So im thinking something still isnt quite right, even though my idle temops are around 26c and max i saw in crysis 2 last night with a 1ghz core was 62c, it still seems higher to me than it was when i had cable ties. I have changed the location of the radiator...its now at the back in push pull with the pull fan mounted on the outside (noisy) frown.gif Thats the only thing ive changed other than adding the bracket

I did have to twist the pump when fitting it again as it just wont hold still. The problem is you have to hold the back of the screws so that the nuts tighten up so naturally the pump moves out of place. Is there a better way of getting it to hold still whilst i tighten up those bolts?

I can see some light through 1 side of the cooler when fitted, it looks curved so lapping might be the answer. I could give it another go over the weekend i guess.

What noise does a faulty H100 pump make? I can hear a high pitched kind of noise from somewhere thats annoying me but i think its the AP-15's on the top mesh.

It's a PITA but it works: use zip ties to first secure the pump to the bracket, thereby allowing you to handle the bracket and pump as though it were a single unit/cooler:

...

1. Wrap the zip tie around a notch on either side to hold the bracket to the pump/block:

394

...

2. Then apply compound and secure the pump to the card with a single zip tie; once that's done, if your careful, you can install the bolts without jostling/twisting the pump around much at all:


369

That pic isn't the best cause I used one that shows the bolts already in place but you get the idea. The red arrow represents the zip tie, of course.

I agree, though...it's a delicate bit of process to get the thing secure without marring the TIM too much; that's the main reason I haven't taken mine apart to re seat or lap or otherwise. LOL ... I'm cool with my temps, though so no big deal.

I think you mounted the bracket first, then you mount and turn the block in the bracket?

becasue mine went on a 6950 i had use the holes with the bit missing and the bolts kept falling through that bit.
what i did was.

1. prepare the card for the 620/920/h70.
2. place the pump in the bracket aligning with the notches.
3. if the pump already has stock paste on place 2 bolts in opposite corners. if not put paste on your gpu 1st.
4. hold the bracket with the top of the pump facing up, holding the 2 bolts with my thumb and finger (this also held the pump in place)
5. i put the card over the top of the pump and aligned the bolts with the holes and slid it down and placed 2 plastic washers and the 2 bolts on finger tight.
6. then turn the card over to put the other 2 bolts in.

i used metal washers over the bolts as they held against the pump to help the bolts stay in place instead of sliding out and i have a changeable screwdriver handle that the hex shape fits the bolts perfectly.
i dont know if this is helpful but i did this method twice and had no issues with the mount

Think those ramsinks will fit under Dwoods bracket with fan mount?
