CPU not seated perfectly due to mobo, is there a fix for this?

I didnt remember to look for this before I mounted my heatsink, but im thinking that this may be the cause that one of my cores is hotter than the other. I have lapped the heatsink, lapped the cpu, and made my own VERY tight way of mounting the heatsink onto the cpu. One core is STILL hotter than the other, you guys think this could be the problem? or will the cpu be seated flat once pressure is applied to the top? thnx.
 
Cores will always be a different temp as they are made of natural material and no two are the same. They also don't get the same amount of load applied to them.

I'm not sure what you are seeing. The picture is a little blurry but it looks like the cpu is installed properly.

If it wasn't installed properly, you'd have no hope of even posting.

Also, if it wasn't installed properly, you wouldn't be able to close the latch on it and it would probably destroy the socket in the process.

Also, that cpu doesn't look like it has been lapped. I can still see the printing on it.

Edit... Wait a minute....take another picture of the whole socket on macro setting. Something doesnt' look right.

thats not my cpu, its just an example of the cpu not sitting perfectly horizontal. I use tat to put load for both cores, and one is hotter than the other by a few degrees. See how the clamp is pressing down on one side? This makes a slant that could decrease cooling performance.
 
Ludicrous

If that isn't a picture of your cpu, why are you asking questions about it?

"remove the clamp and see what happens"? Wait........i need to stop laughing first.

Is this the childrens hour or what?????

EDIT!! By the way.....any picture taken like that loses perspective due to the distance and angle and the shape of the lens.

??? what the hell is your problem...


thats what you do if you remove the IHS. you just pop the clamp off. and put the heatsink on. the heat sink is now your new clamp. not hard at all. so if he's saying the clamp is putting to much pressure. why not just pop it off. its as simple as unlatching it. and twisting it off. only problem is the cpu will probably fall out if its sideways. so you have to do it while its horizontal. but i would expect you would have to do that anyways so you can mount the heatsink.

wow GG Each core has different temps but what are your temps on each cause if its just a bit higher than other i see no problem. but if its by a large amount than yea i would be worried.
 
Correction

It isn't my problem.....it is his problem.

And the problem is that he does't have any idea if the clamp is putting too much pressure on the cpu. That picture wasn't of his cpu. He doesn't even know if he has a problem. He seems to be looking for a problem where people have already told him there isn't one.

And then you come along and tell him "sure.....take off the clamp".

I'm still laughing by the way .....whether you think I have a problem or not.
 
all im saying, is I read about that on a sire where they were reviewing high end coolers, and they noticed that problem, and took pix. I want to know if 1. This may be the cause of the difference in core temps, and 2. How to fix this? Im thinking it doesnt matter because of the crapload of pressure the heatsink is putting on the cpu (custom mount) so that by itself flattens it out...but im not sure...

on another note, lets me mature here, no need to laugh at people.
 
Excuse me?

For one jph1589 stop being a troll.

enz660 are you able to take any pictures of your custom mount?

The entire thread was misleading. It was started on a false premise. Don't call me a troll because I was the only one who noticed that.

Most people would have just looked to see if the thermal compound was spread evenly. That would have answered the question for most people. Far be it from me to discourage someone from wrecking their motherboard though. I'll leave that to the others in the thread. Adios!!
 
That clamp has no affect on the mount. It just keeps the CPU in place. Because the IHS is higher than the clamp the heatsink will never touch the clamp.

When your heatsink makes contact with the IHS, it doesn't need to be horizontal, just flat. The slant doesn't really matter basically. However, if it has a concave IHS that could be part of the reason why you get different readings.

My theory is a little different as to why the two cores always seem to give different readings and by such a large margin. Now, I don't know to what extent AMD and Intel calibrated their thermal sensors but if they don't calibrate both cores to the same range there could be problems. Lets assume core 1 is 2°C hotter than core 2 for whatever reason. Now lets say that core 1's sensor also reads 3°C hotter than it really is (most sensors read +/- 3° before they are calibrated). Then lets say that core 2 reads 3° lower than the actual temp. That means that there's a delta of 8° between the cores. Thats enough to make any overclocker concerned ;). I lack the necessary info or hardware to try to prove this so it'll just stay in my theory box until someone can prove or disprove it :).

you don't ruin your motherboard by taking it off.. dear god. its simple enough to put it back on. your just being arrogant here. no point in not trying.


yea. 4-5 degrees diffrence isn't anything to worry about. but if you must find out why. try this.

mount the heatsink the opposite of what you mounted it before. like. a complete 180 turn. and see if it does anything. if it does. you probably did a bad lapping job.
 
Or maybe

Maybe he should try something that will give him an obvious conclusion instead? If the thermal compound is spread evenly over the heat spreader when he removes the heatsink to look at it, that will tell the story.

Maybe that is too SIMPLE??
