Windows 7: PAVILION S3100N overheats

19 Feb 2012   #1

win 7 ultimate 64 bit
PAVILION S3100N overheats

It overheats and shuts down. Very snall case. A friend says he thinks its a bad hard drive. I dont buy that. In fact i have googled that these pc's have that problem but i found no fixes that i havent tried already.
I think i can fix this but i need to hear from people who know more than i do to see if this is doable.
The cpu has a massive heatsink mounted sideways with a fan on it. The fan is very very fast and loud. The air flows from the fan thru the heatsink and out the back. I can use windows settings to have the fan come on and off enuf so that the problem is taken care of but its awful noisy. The fan is the type with 4 pins, there are no molex connectors at all and there are no other sets of pins on the mobo except for the one for the cpu fan. Cant use a different case as everything is proprietary, even the darn main atx connection is very small!

I propose to first find a fan that will fit the cpu but has only 3 pins so that it runs all the time but hopefully a bit slower and quieter. Then i propose, since the mobo only has the one set of pins for a fan, to splice into the wires for the cpu fan and connect a small fan that way. The fan will sit on the back of the case and expel hot air, same as the cpu\hs\fan does.
I believe, if the splicing is allowable, that that would solve my issues of extreme noise and overheating. Can i splice like that? I figure its ok as if there were molex connectors i have seen fans stacked on one line and this is only one extra small fan, fan being about 2 inche wide all around, thats the only size that will fit the space at back of the case.
Sorry this is so long.
Thanks for your help.

win 7 ultimate 64 bit

I learned something i should have realized. The existing fan is standard 7 cm square. So i took another fan from another hs\fan setup and installed that fan.
This new fan is only 3 pins so it stays on all the time.
There is a difference. The case itself doesnt get hot like with the original noisy fan and the air that is expelled is cool where the air from the original fan was very warm, so things are improving here it seems. But i might only be part of the way home.
A few questions though:
1- is there a prog i can get that will make the machine work a bit so i know all will be well under stress of normal things like playing a minor game, using word processor, internet, file transfer, the normal stuff? If so is it readily available?
2 - I also installed speedfan. Is there anyone who can help me with it a bit so that i can do the learning a bit later, lol? I dont understand the settings and wordings inside speedfan. I do notice in one area that there are plus marks, the v shaped plus marks, but also a down arrow and one fire sign, which i am guessing that speedfan is saying its too hot.
3 - Can anyone answer my question about if i can add that other very small fan by splicing it into the line that services this new fan? I may not need it now in this case but i would sure like to know the answer for future ref. Or point me to an online tutorial that shows all about using wiring to changes voltages and such things? So far i havent been very lucky in my google search for what i want, mainly about the splicing.
thank you
