Chip Cooling=removing metal behind chip

[oc jason]

Well i took my antec case out,and measured where the socket is positioned on the back side of the metal. Took it outside and cut about a 2x2 inch hole same size as the socket. Put board back in and was pleased to see the intire socket make up perfecty wide right side panel off, i just figured insted of it just building up behind board, or slowly making its way out id give it a direct hole to escape thorough.

I now run 1c cooler, at same speed, but i also was able to acheive this temp while takign away a noise 103cfm, 120mm sanyo denki intake fan, not alot cooler but QUIETER.

Once my 5 80mm Panaflows come in im gonna use 2 intake 2 exhause, and 1 for the socket hole, Just install it as an exhauset fan, and cut the hole bigger to fit it, venting directly out side of case, the space between the fan and the board will have a duct helping to catch the air. Ill post pics when im done

There was an article on the front page where Ed cut out the PCB inside the socket for extra cooling and it got him no where. I dont know if what youre thinking of would be worth it...but if you already saw 1C lower temps, give it a try i guess. Let us know how it went.

When I first read it, I thought he meant he cut a hole behind the socket on the motherboard tray on his Antec, now I don't know.

Are you using an in socket thermal sensor to measure these temps? Cuz if you are you're simply cooling the pcb where it attatches making it THINK the cpu is running cooler when in fact it might not be any cooler.

If you did cut out the area on your mobo plate right behind your socket, now it will be easier to put an Alpha of Swifty on their with out having to take the mobo out! I'm thinking about doing something like this myself since I can't find the MG II in stock anywhere and will probibly go with the Alpha 8045. Thanks for reminding me! :)

Yes all i did was cut out the metal behind where the socket is i the case. If you make a hole big enough it will be much easier to mount and dismount a HS that uses the 4 board holes to mount it. It may give false reading b/c i am using an in socket thermal monitor. But i was under teh impression that it touched teh rear of the chip, not just the air arond it, if that is the case and it does not really touch the chip, than the reading are already false.

Also if it is lowering the temps of the air around it, and not really the chip itself, in essence it will lower the chip temp due to cooler air arond it, so maybe it will help maybe not.

I'm not sure just how effective doing this is overall, but I have noticed the same thing in the past- ie.: back of the mobo gets HOT sometimes. Particularly the areas behind the cpu, and north/south bridges.

In one of my old k62 rigs (a few years ago- I no longer have the case) I put a 486 fan in the back side panel exhausting behind the mobo. Case temps went down about 2 or 3 fahrenheit, cpu went down about 1f.

It does seem to me that if the whole mobo can be made slightly cooler by this than it helps a bit......maybe someone into both modding and testing will do some formal tests- and write an article?

Every so often you read about someone who mounted a fan blowing on the motherboard behind the socket and getting a few degrees improvement in temperature. It's sad to see people buy into this process because all you are doing is fooling the in-socket thermistor by lowering the temperature of the motherboard around it. I seriously doubt this "trickery" has any positive impact upon the CPU core temperature. Furthermore, it may give the uninitiated the false sense of security that they are running their CPU cooler than it really is running at. There are enough issues arising from using the in-socket thermistor without compromising its accuracy any more than it already is. Just my $.02 worth.

i did the same to my old case, but it was for mounting my waterblock, cooling the back of your cpu is cheating if you use the built in thermal didode, as it cools the diode

[rogerdugans]

okay, I understand that just cooling the back of the cpu is pointless; my question (along the same vein) is this:

If your mobo runs hot, would getting better airflow around the back side of the board actually help? Not considering cpu temps at all here (so maybe it should be another thread?), just motherboard.

It does seem to me that you would be cooling a much larger surface area and therefore it would in fact help to some degree.

Any other thoughts?

[dreadlord79]

It seems to me as well, that maybe we spend a little to much time thinking about cooling the chipsets and never spend any time on the components that make it all work together. The traces on the mobo are carrying current and I'm sure that if the over all case temp is lower, you might even have a more stable mobo with the extra heat from it being disappated. Just my $0.02. :)

[ButcherUK]

Unlikely trace cooling will affect anything, they don't exactly run hot you know. As for general cooling, yes but the front is a better bet as that's where all the components are.

[dreadlord79]

I wasn't really talking about cooling the back of the Mobo, sorry if it came out that way. I was just saying that maybe an all over cooling solution would be a little bit of help. I'm sure that my system isn't having any trouble and I'm sure that most of the folks on this board have enough fans in their systems to keep everything nice and cool.
