E8400 strange temps...

Ok, well I just got done building my computer XD. My specs are:

Two 9800 GTX's in SLi
E8400 Stock Clocked
4GB DDR2 800
800W PSU
Antec 900
500GB HD 7200 RPM
EVGA 750i SLi

The cooler I got is strange because even at a stock clock, I get 51C IDLE!!!!!!!!!

My cooler is this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I even tried putting the stock cooler on, and it overheated on boot-up.
Is there something wrong with my cooler? Or is there something wrong with the CPU itself?
Whatever is wrong, could you guys tell meh, and give me a solution. Thanks! :D

nice set up but the 750i yuk!

your got a lot of gpu heat and psu heat but with the 900 that is high temp - you should be 35-42c

whats the room temp? is it 85-90f thats why!


you have a crappy cooler - the fan is small and slow - the cooler is ok - you have a 2300rpm 90mm fan that is built in.

you need a 2800rpm fan or 120mm 2400rpm

120mm fan at 2000-2200 is optimal - with some mobos you can set speed by %

so a 120mm fan with 2400rpm set to 80% gives optimal cooling

your temps are high - whats going on idel? maybe you boot into orthos? thats a joke!

reinstall the cooler with good tc - if still high toss it

get the xig 120mm or thermal right

E8400@GA-P35-DS3L (stock cooler and default frequencies) With core temp I get like 53-55C on idle and 71C on full load, room temperature some 24 in the morning 30-34 during the day (well it's summer), which means speed fan is like 10C degrees lower. Maybe I mounted the cooler wrong, took it out of the box and pushed the pins (guess it has the pre-applied thermal solution from intel). Is there some sticker on the cooler I should have removed because I looked and did not seem to be.. Case is an AC Silentium, which means 17cm in total and roughly 15.5cm from the cpu to install a new cooler (thus thermalright 120 out of the question), any suggestions? (maybe the Tuniq 120). Any real danger at these temperatures? (I am not really that interested in overcloacking, but I do not want to fry anything) Also the heatsink on the cooler is rather cold, but then any very small overcloack is unstable, so either i mounted the cooler wrong or the mobo (latest bios) reads incorrectly (some 44-49C in bios).

A significant percentage of 45 nanometer processors are known to have defective DTS (Core temperature sensors) which "stick" at Idle, and won't indicate the actual temperatures. Sensors can be tested by using Real Temp 2.6 - http://www.techpowerup.com/realtemp/

Read the Real Temp documentation - http://www.techpowerup.com/realtemp/docs.php - to understand why Real Temp 2.6 is more accurate than Core Temp 0.99.

If you want to understand the difference between CPU temperature and Core temperatures, and how to properly test, calibrate and monitor your temperatures, then read the Core 2 Quad and Duo Temperature Guide - http://www.tomshardware.com/forum/221745-29-core-quad-t...

Fine... have it your way real temp reads the two cores values as 62-62 under full load (3x winrar multithread doing a huge archive will do the trick), idles at 46-48, test sensor shows lots of values each time i test (9-7, 9-8, 10-7, 10-8, 8-7) but most often 9-7 . I only asked if I should worry not to follow some guide and do the maths...

:pfff:  Bovine faeces!, @ OP this is mine with an Arctic Freezer Pro 7 I would suggest removing the heatsink cleaning and reapplying paste and then re-attaching the HSF.
June 30, 2008 10:17:58 PM

Yeah, reseat the heatsink again after you apply some good thermal paste. (I really hate pushpin heatsinks!)

Here's mine @ 3.6

honary poster or honary noob? my mom can clock an E8400 to 3.6 and yes that bad hsf works fine for that low oc.

now try 4.2ghz with that! of coarse the E8400 is a noobie chip you need an e8500 - intel has lots of products and the first E8400 where disappointing as is your oc.

i suggest you get a real cpu with 2 dies and 4 cores - its called a quad - take to asprin and call me after you post your 3.6ghz temperature with the quad

July 1, 2008 6:22:28 AM





dude 3.6ghz with an E8400 is really old. A quad core came out in 2006 called the qx6700

it was replaced by the q6800 and the q6850 then we got the 9650 and now the 9770

the Q6600 go will clock to 3.6ghz each and everyone as posted by me in aug of 07 - ya last year!

get with the program if not talking a Q9450 with 450-500fsb we do not need to hear about systems that dell can build!

o ya my endless self promotion! :

artic is crap! get a real cpu and then you test a real cpu cooler - o ya i did that:

http://www.tomshardware.com/forum/250728-28-xigmateck-t...

not that anyone cares but what the heck its all fun!

Are you 15 years old or drunk or both?
Maybe a little bit egotistical?
Who said anything about Dell built systems? I built mine myself.
I offered a temperture comparison for comparison purposes for the OP to another poster running same set-up.
I use a Vendetta cooler, not an Artic, or were you too drunk or full of yourself to notice?
Grow up and learn some proper grammer and spelling.

@kpo6969 Yes your set-up is similar, thanks for the info, i will be upgrading that lame cooler. Two choices come to mind, the Tuniq 120 Tower or the Zalman 9500, but mainly what I want is a silent cooler that can also do a good job at medium rpm. I don't think that overcloacking to 4.2Ghz would make that much of a difference in games (maybe a 10% gain at most), so the main purpose to do this is either to brag about it or to have a leverage in video editing or 3DS or any other CAD software (especially if you have quad cpu). Sure, if you have a good cooler then overcloacking is a bonus for all the money you spent, but applying fashion to cpuz, well that's funny and lame: dude that is so last summer, now they are wearing quad :D

I recommend the Zalman paste with a brush for good coverage!

A Quad eh?, what like this? .
I would suggest that you brush up on your grammar and spelling.
