Motherboard temperature

Compaq Presario 3020IL

Windows 7 x64

 

I would like to know the max temperature my motherboard can handle

I have seen it just touching 60 C under normal use, but goes up during high cpu usage

What is the max temperature limit for MS 7525 motherboard?

Re: Motherboard temperature

While the motherboard may have an operating temperature sensor, there is usually not much concern for that.  The most important temperature is for the CPU (processor).  Several software applications can monitor the CPU temperature for you if that is what you desire.

Re: Motherboard temperature

Yes the motherboard have a sensor and I am using speccy to view the temperatures, processor goes upto 58 C and I know this temperature is safe for processor. My major concern is motherboard as I dont know 60C+ is safe for my motherboard or not. I would realy appreciate if you know what are the temperature limits for the resp hardware

Do you have an exhaust fan for the case? Maybe they don't do this anymore but I am amazed at how older machines have no fan, or even reflects the reverse logic of air flow - it should be intake from the bottom/front to higher/back. The vent in the back of most towers are clearly for an exhaust fan, it's close to the CPU so it'll help exhaust that heat. Not only do some machines not have one, sometimes that's turned into an intake by virtue of a shroud that goes to the CPU with the fan blowing down on top of the heatsink, (old HP Pavilion, unlike Dells that has an exhaust at the back but no fan directly on top of HS) and today I just found one (non-HP) that has a filter on it. A filter makes sense in the front for intake, not the back.

 

While I don't have technical info for you as far as motherboard temp, you can greatly reduce your case temperature (and therefore all component temps including CPU and board) by just spending a few dollars on an exhaust fan, if you don't already have one.

 

EDIT: I just looked up your system and it's basically the same era (sockeet 775, C2D) as the one with the filter which I worked on today. It really is the simplest thing to add a fan, and possibly correct some ridiculous installation that makes it even warmer.

Re: Motherboard temperature

I'd like to know the max safe temp also. One part of my motherboard seems to run at 87C constantly which would explain why my fan whirs away noisily all the time even when my CPU's under 40C.

87C seems unlikely, are you sure that's not 87F?

 

My question is what has been done already. Aside from installing an exhaust fan in the back vent you can upgrade the heatsinks on the chipsets as well, and even just get an after market case for full customization, (motherboard is standard Micro ATX) in which case (no pun intended!) there are lots of options for optimal ventilation. Yes that's a lot of work but it may be worth it in the long run if the machine is out of warranty anyway. You only have to mount the motherboard, power supply and drives and not do the rest of the setup.

 

By the way, vertical style CPU coolers with the heatpipes going up will direct the airflow toward that back vent anyway, some allow you to mount two fans in a push-pull setup, which would allow overall case cooling. Compared to the typical stock cooler that just blows downward on a heatsink over the chip it makes more sense for the system as a whole. That would be a fairly simple upgrade, you should be able to put in a 90mm one with no problem, coolers with 120mm fans and up you should measure and note the dimensions to make sure it will fit the case. This would be just one step beyond the case exhaust fan and not that hard to do. But if a case fan hasn't even been installed, do look into it. Note the size (vent is probably for 80 and/or 90mm fans) and look up one of the popular online stores for one with decent airflow in CFM and go from there. It's a simple matter of plugging it in and four screws to mount it.

 

EDIT: Looking at a picture of the motherboard for this machine it seems there is only the CPU fan header. If you decide to try a case fan make sure it also has the large 4 pin molex connector to connect to the power supply, sometimes they only have the small 3 pin plug that goes to the headers.
