Gtx280 Ihsless

I know lol, when whe3ls on overclock.net pointed that out I was laughing so hard... I wish I could sign up on that forum that posted it as news of a 200b chip and show them this thread to stamp fail on their face.

:rofl:

Got a question...

Why would one want to do this? Wouldn't it be better to leave the IHS so that you can tighten down blocks or pots or evaps tighter and get more pressure?

The IHS is there to prevent damage to the core, distribut the heat, and allow a better tighter interface.

Is my thinking wrong on this?

Sometimes the IHS makes crap contact with the core. Cutting down on the number of thermal barriers between your heatsource and your cooling will also let you control temperatures better. Direct core cooling is ideal but I agree, keeping an IHS on keeps us from crushing cores. I know I use some insane clamping pressure and have in the past crushed cores.

Thanks. I appreciate the response. I was a little worried about the way I worded my reply. I didn't want the OP to think I was questioning his methods as it's obvious he has alot of experience with this stuff. I was just curious as to why.

Would it be beneficial to clean the IHS, lap it and reseat it with some good nonconductive TIM? The glue or that grey goo stuff would have to be carefully removed and replaced.

I'm curious about this, because I'm learning watercooling and will be doing my first build and would like to get the most out of stuff, but want to be careful not to risk anything (or not take risk of crushing something), and thought if I could reseat the IHS carefully I might gain a better Interface while still protecting the core.

I am kinda paranoid because these are very expensive cards. I also am new to watercooling so would need to be a little more careful as I don't have experience with the feel of pressure and how much force to use yet. hehe :)

is the die really flat?

For all of you that are saying its a 290 or a 55nm 280 it is not. It's just a GTX 280.

If you're worried about crushing a core, don't even remove the IHS. There is a much higher chance of ripping the core right off the card while removing the IHS than crushing the core without having the IHS on there.

To put it bluntly, the people with the know how to remove an IHS do it for the temps; they know how easy it is to break a core.

Beautiful die.
Great job.

i dont i was just letting you know you,

what are the dimensions of the IHS please? Thank u! :)

I love that TEC Idea, its like it was made for a TEC!

Any idea if the DTek GFX 2 would still fit, with or without the uni-sink?

agreed... I'd like to know that too... it seems like it was held by cheap thermal paste... adhesive thermal paste??? anyway if you can please let me know i'm thinking of lapping my IHS on my GPU and im hella scared I'm thinking if i'm gonna do it i might as well fo it right and pull the IHS off, lap it and put real good stuff on... and i never understood how come the stockcooler doesn't work anymore?

It's not working anymore only if you leave the IHS off because if you do, the standoffs and other chips are keeping the cooler from reaching the die. I imagine the difference between IHS and no IHS could be 1-2mm.

I was nervous when I popped my 8800GTS but there was space enough for razor blades.

I haven't even thought about popping my 9800GX2, though I have a EK block on it so it wouldn't be wise.


Good show Cpt_ now going to do that with the next card that comes out? :D


Popping the IHS as stated is a two sided blade but if your not doing any extreme mounting like pots or anything else then shouldn't have to worry say if your mounting an MCW60 or similar. Still need to be gentle but just knowing that the core is bare (save tim) on the block can be comforting when your looking @ your temps.

Planet, what kind of temperature drop did you see?
