CAN MOTHERBOARD RESPONSIBLE FOR HIGH CPU TEMPERATURE

[PANKAJ SINGH]

I am not sure if this question ever arise earlier but I am putting it in the forum and request the member's and responders that kindly only those who are highly chip level technicals reply to this question so that people may get benefit and understand it. In very simple words i want to ask that,,,,,

Can motherboard be responsible for rising CPU temperature too high even though the temperature controller censors are located within the CPU. If yes, then kindly explain it how.

 

[Deders]

Is there a particular CPU/Motherboard you have in mind?

 

[Billb2]

Hmmmm.

If the motherboard gets warmer the CPU socket will get warmer. If the CPU socket gets warmer so will the CPU. How much warmer? That depends on a lot of other factors.

It doesn't matters which CPU. the simple question I asked is "can motherboard be responsible for rise in CPU temperature too high and if yes then explain it technically how." Motherboard doesnt get warm, the temperature of motherboard is stable at 45 celsius. With high temperature i mean going beyond 100 celsius. For your information to those, who are non technicals, maximum CPU tolerance capacity is between 60 to 90 depending on your CPU configuration.

Further I also request Anandtech technical experts to kindly reply to this question to provide the information. Thank you.

It can matter as not all CPU measurements are accurate. The AMD64 Brisbane sensors for instance were renowned for being inaccurate. There are also more than one temp sensor in modern CPU's, and getting an accurate reading can be confusing when Intel and AMD have different methods. for instance:

A bit more info would be helpful, but if you are talking about 100c temps then I would say that has more to do with the cooling solution, and whether it is effectively seated with a suitable thermal paste. (Also is this under load or when idle?)

Despite coolers saying they are compatible with a range of motherboards (1156/1155/1150 etc.), I've found that fitting one of these coolers to an 1156 board has resulted in much worse results than a lesser cooler that was designed at the time that 1156 was prominent. It caused my CPU to reach 100c and cause throttle, my previous cooler with less heat-pipes and surface area achieved 60c under the same load at the same clockspeed.

I love how some junior members sign up, and immediately show a bad or elitist attitude. The people here are here to help others, so you will get better results and help by not immediately arguing or telling people that their questions aren't applicable.

Maybe if you were clear on what you were actually asking, you would get an accurate answer from the 'technicals'. And of course it matters what CPU is being used, as well as the cooler, socket, airflow, and motherboard layout and design. If you want to get an accurate answer, you need to provide the specific hardware you are asking about. There are too many different variables that affect CPU temperature.

If you read motherboard reviews on some sites, they take a thermal reading around the various parts of the motherboard, and it can vary by several degrees Celsius (especially around the CPU socket) depending on the layout and design.

Wow, all those who are visiting to this topic is just posting this and that but no one is replying for what exactly been asked in very clear words which been asked in very simple words and italicized with bold and underline. Please read and understand the actual question/querry been put there. Once again i am repeating my question again in very clear words below:-

Can MOTHERBOARD (no matter which type and socket but ofcourse those who support dual core and above processors) be RESPONSIBLE for rising the CPU temperature too high even though the thermal controller censor is located in processor. If yes then explain technically how.

Hope the readers/responders will read it carefully to understand what is being asked here and will response if they know the chip level technicals.

I once again request anandtech technicals also to reply to this post.

I also request to the visitors that please dont reply if you dont know the answer for not making it unnecessary argument which may take the main querry away from the point, Thanks.

Six posts here, and you are now on my ignore list. A new record.

Welcome!

A motherboard on it's own won't make more than a few degrees difference in temperature.

The heat usually comes from the amount of voltage and the amount of electricity needed for whatever load is being run.

Different motherboards might run different voltages, especially if certain bios features are enabled. For instance boosting all cores to full turbo boost can sometimes be enabled by default which will usually come with a boost in voltage, but it should still be within the specification of the CPU.

This is why when you talk about temps of 100c, it won't be the motherboard on it's own, but it might be a cooler that doesn't quite fit right.

With God, all things are possible. So the answer to your question is yes.

It's not a helpful answer, but it's as specific as you can get with no specifics.

I think this is one correct answer. I can see various MOBOs providing different voltage to a CPU and thus causing higher temps. We know some default to full core turbo with Intel chips. When using a stock cooler on something like a 4790k this will lead to thermal throttling (happened to me, though the stock cooler throttles at full stock anyway).

Another issue I ran into, is the CPU hold down bracket on the MOBO. I had one that was manufactured wrong (dunno what else it could be) and it was interfering with the stock heatsink and preventing it from mounting correctly, thus drastically raising temps.

Agreed.

So can a motherboard, which is itself not generating an excessive amount of heat, cause a CPU to run abnormally hot? Aside from the aforementioned physical design issues, if the motherboard were incorrectly supplying too much power then the CPU could overheat. I've never heard of it, but I'd think it was possible.

Is this happening to you or is it just a theoretical question?

Ofcourse I am facing a high CPU temperature problem. I tested the same processor on 4 different motherboards and on 1 motherboard the temperature is going too high even though i kept all the option close/default in BIOS. I even replaced that model motherboard with another piece of same company and model which is giving high CPU temperature but the same thing happening on the replaced motherboard also. So i created this thread to know the technical reason how could motherboard be responsible for CPU high temperature.

 

[Deders]

It's most likely because either there is a gap between the top of the CPU and cooler (caused by bad fit for whatever reason), or too much/little thermal paste applied.

For future reference, pretty much everyone who posts in this forum will know that depending on the kind of CPU, it will tolerate either around 60c or 90c (actually 100c, but 90c is safer)

And because there is such a variety of hardware out there, it really does help to give info about the hardware and situation. We might know more than you think.

 

[dave_the_nerd]

Older motherboards used to have their own temp sensors. The oddball motherboard could be reporting a different number from a different sensor.

This is why it's actually important to know what kind of CPU and motherboard you have.
