If you want to be part of the delidding community: Get any INTEL (Haswell, Haswell-E, Sandy-bridge or Skylake) and I´m sure you could boost those temps! FP
That was a Trinity APU that the OP delidded. It uses ordinary TIM underneath the heatspreader, just like an ordinary Intel chip does. The FX line has excellent heatspreading capabilities because those are soldered underneath. But AMD went to TIM on their APU lines until Godavari.

Also, all Intel "E" processors and all Sandy Bridge and earlier are soldered. One reason a lot of people here still swear by their 2x00K Sandy chips is because they overclock so well thanks to being soldered, and because of that, they are still very competitive even after nearly five years.

And if you want to hit 5.4 GHz on a 4350 with temps under 60, you're going to need some LN2.

Dude, you obviously don't have a clue of what you are talking about. You don't even know how to uh, tell falsehoods well.

Lapping to higher grits flattened out the surfaces so much that contact area was reduced more than was mean bondline thickness, reducing thermal transfer.

Of course, when dealing with one of the metal pastes, surface coarseness may cease to be of issue due to the way it behaves (or the way I think it behaves), and lapping may be of no real value. But going from the nickel surface to a 400-grit lapped copper surface will improve things. 800 grit might be better, if you're using a conventional paste. Mirror finishes are basically pointless from a heat transfer PoV.


Well that goes against what most people think about lapping but it may be true. Most people lap to a mirror finish. I stopped lapping cpu's because I lost track of what they were after I put them away. I used to lap heatsinks also. It is a real lot of work to get that mirror surface. Not worth it imho.

Also, I have not experienced problems with mount pressure using my Noctua NH-d14. Might be a different mounting mechanism than for your HSF? And yeah totally lap that IHS now that it's loose. Take it to 400 grit, no sense in going any further.


400 grit is really, really coarse sandpaper. All it is good for is scratching. I probably would start with 400 grit and work my way up to 2500 grit.

WhtRabbit If you do try to delid your Fx-xxxx guess i'm the only one thats going to say it'd be safer to just get some pliers, like one thread i seen read http://www.xtremesystems.org/forums/showthread.php?289389-I-just-delidded-my-newly-bought-FX-8320-PICS, and put it top down in a pan while holding it, but rather than what he did, use a probe thermometer, put it in the pan, wait til it hits around 365, put cpu in the pan IHS down for five seconds while holding it with the pliers, pull out, and try to pull the IHS off with a pair of precision tweezers would honestly try to get another set of hands to help then after that, the solder thats left is going to be the problem, could lap it as far down as you can, use some liquid paste, and that should work, honestly, if i got it off, i'd try to post, if it actually posted, i'd stack a few coins/folded tin foil to get past post, if it hit windows and loaded, then, i'd do the lapping and liquid paste, but its all a risk.
