Inspiron 9400 + I9kfanguy + Overclocking

Hello everyone!

There is something that has been bugging me with my lappy. It has the tendency of waiting till the gpu reaches 80c to turn on the fan on high then it lowers the fan again when it reaches aroun 70 or so degrees. This behavior worries me, I don't want my gpu being at those temps.

I have been looking for a way to control the fans so I can have them in high speed all the time. I heard of this program called i9kfangui. But to my surprise in the official webpage says that they don't recommend installing them(Core Duo users only, so i9400 applies) yet till a newer version is released.

Right now I have my laptop OC @ 300/800 because I don't want them too high or too low. So I was wondering what exactly is the problem that i9kfangui have with Core Duo processors. Is there any way to use the program right now with my i9400? Is there any other way to control the fans of my lappy at will?

Another question is, is my 300/800 a good and safe oc? I manually oc'ed it but I am wondering if you have to move both memory and core at a same %? For example oc both a 25% more instead of just "randomly" like I did or it doesnt really matter?.

Sorry for my weird English, is not my first language.

 

I9kfangui is the only program to control the fans from what I know. And if I did my math right, your clocks should be 300/790. I do not know if 10 more mhz will do anything to hurt your computer, but that is my input.

 

Can you tell us how you calculated that 300/790 would be the right setting? How do you know/calculate that?

I hear you about the gpu temperature being so high. I find it really does fluctuate from low 60's to low 80's depending on use. What is an acceptable temp when the warning is set be default to 93 degrees? Don't want to wear out the fan either from over use right? (better then the gpu mind you but if the fan goes chances are the gpu could go too before you knew it)

 

I'm guessing/hoping that everyone elses 9400 with the go7800, and not just mine, has the GPU temp idle up to ~81C then the fan cools it down to ~71C (and then repeat process). It just doesn't seem right to me that the GPU can get that hot when not running any 3d apps.

I've tried several different drivers, no OC'ing and some OC'ing... and the temp is always the same.

Also, when I haven't OC'ed, the GPU temp is actually at about 62C after running 3Dmark05...

Anyone else worried about the temp situation, or am I just paranoid?

 

centrino hardware control might work in lowering tempts.. by adjusting the voltage settings of the cpu. My old asus w3v was 5 degrees cooler with the centrino hardware control program.. not too sure if its compatible with the new duo core processors.

 

SpeedFan is also a popular program for controlling computer fan speeds... I don't know if it works for laptops though... as I haven't gotten it to work on my laptop yet.

 

I use speedfan on my desktop but I don't think it will work on laptop

 

I don't think it will work with the Dell's Inspiron series. I still hold my trust into the i9kfangui, and wanting an update for the e1705.

 

So I'm guessing these high idle temps are an across the board situation for all i9400/E1705 users? Seems that I read somewhere that newer die construction allows for these "warmer" temperatures to occur safely... not sure specifically though.

Any E1705 users have cooler GPU temps when the computer is idle and the lcd is on? If so, what was done, or is this stock?

 

Apparently the new 83.90 mobileforce drivers from tweaksru are fast and keep the gpu at around 60 degrees accoriding to Garbuckle over on the main 9400 thread under reviews. (sorry if this is cross posting). Head on over to tweaksrus.com and give them a try and let us know your results. I can't be bothered while I wait for my replacement 9400 to come on monday (lcd died on my first one after 10 days!)....

 

Ahh, bummer about the lcd. I can feel your pain -- I got the E1705 because I had to refund a MS-1029 from CyberPower System because... well... it's a long nightmarish story.

Anyway, the 83.90 drivers were actually what I was running at the time of the post (I'm back to stock atm to compare the temp here). The temperature situation stayed the same. I guess it's the way the fan is just set to run -- stay off until reaches 82C and turn on until 71C, but run the entire time a 3d app is running to keep around 62ishC. There's an anomaly, however, that at random the fan will continue to run at low speed while there is nothing but an idle desktop, keeping the GPU temp at a nice 59C. It seems like something triggers the fan to turn off, though, without provocation, and it returns to the 70-80 fluctuation. ::I've only noticed this because I'm always looking at the temp... I think I've become obsesseed::

EDIT

I've now noticed that the stock video drivers are actually keeping my GPU in the lower 60s range about 95% of the time. As with all systems, it's safe to assume results and temps will vary from one to the next. The stock drivers only score about 100 pts lower on 3dmark05, so I'm sticking with these. NVtweak will satisfy me if I feel the need to OC.

 

80C under load is quite acceptable, 80C idle would be a whole different story ...

I wouldn't worry at all if your GPU is reaching those temps under load... Spec is well over 100C
