Why an IHS? Why not soldered

[Shadow_Storm56]

This is a simple question..... Why do they have an ihs? considering most coolers function better when delidded....is it due to the expectation people will apply the cooler wrong and distroy the cpu? Another question.... why do they not solder every IHS as it has a massive temperature decrease verses no soldered. Why not give an option without an ihs? Like look at water cooled video cards...no ihs and if you can dissapate the heat you can keep ur card stable at like 35c in a really powerful card

I'll find my post explaining it all and post it here

The notion that coolers work better when delidded isn't accurate, and der8auer wrote a very informative article on why IHSs are not soldered.

For the question of soldering over thermal paste. Money, it costs more to solder it.

 

For most chips thermal paste is fine.

Start here and keep reading, there's boatloads of posts explaining it.

That's not it, according to the source. I invite you to read it

Has nothing to do with money, soldering small chips can destroy them, and even if they survive the process, it can destroy them later down the road due to heating and cooling.

Really? because graphics cards have no IHS and they stay way cooler water cooled..... then again i guess they are designed different. I guess that makes sense that soldering can hurt....but geez somthing as powerful as the 6700k gets soooo hot even on water but if you have what i have now the 6850k i can clock it as hard as i can safely go and get very much lower temps....just because it is soldered. I shall read some of the articals later

Ok i see why soldering can be bad, especially on smaller cores.... but why not have no ihs? just thermal paste right to the core... same as a gpu. I assume there is a reason

Some GPUs do have an IHS, some don't, I suspect it's a matter of whether the IHS is needed to spread the thermal load (as chips become more dense, cooling it with direct contact becomes harder and an IHS can help with that).

 

Don't take my word as gospel, I am quoting the article

I thunk it might be a protection measure, GPUs ship with the cooler already installed, but naked CPUs might get damaged very easily.

Integrated heat spreaders are on every CPU on the market aside from some SoCs.

That's due to using better thermal interface material (TIM) versus what they're using.

No.

The IHS is the intermediary between the core and the heatsink to spread force and allow more efficient cooling of the CPU's cores.

They still have an IHS. This is due to air being a less efficient medium for cooling versus water.

CPUs have a smaller surface area compared to the GPU

 

the IHS is there to increase the surface area and to protect the die

No but like a water cooled cpu can still hit in the 70's when overclocked...but a max overclocked gpu will rarely hit 40c so why?

Depends on the workload and the build. My CPU and GPU are usually both around the 68C mark. The CPU is also smaller which contributes to the loss or transfer of heat.

Most gpu makers don't plan on people taking apart their cards it voids the warranties for most gpus, but for cpus people can change out the coolers, there was a time were cpu came without an IHS and if you tightened the cooler down too much it chipped the corners, and broke the chip, the only reason for the IHS on the cpu is to protect the die.

 

As for soldering the IHS vs thermal paste, it cost a lot less for the company to buy thermal paste then to buy indium, nickel, gold, and a few other metals, apply them and do all this.

Does anyone know that the original reason for the IHS was to protect the die.

Is this a question or statement?

The type suggests question, but the punctuation suggests statement.

Literally mentioned it right before your post.

Both a question and statement.

[NumLock21]

The only chipset with a IHS is the X38 and X48. Does it use TIM or Soldered is another question.
