please help with E8400 temperatures - Overclock.net

My rig

intel E8400
XFX alpha dog Nvidia 8800GT
Abit ip35-e
kingston 800 MHz value ram CL-6

from day 1 of my purchase, i get really strange temperatures concerning my CPU cores
Core temp shows

Ideal condition
core 0- 50 - 52 C
core 1- 54 - 56 C

100% load
core 0- 65 - 67 C
core 1- 68 - 70 C

Tj Max - 105 C

Everest shows similar core temperatures with an overall temperature of 60 C

I recently overclocked it to 3.6 GHz by increasing the core voltage to 1.325 V though it shows 1.24 V in idle condition (1.225 shows 1.18 in factory condition by CPU-Z) and to my surprise the core temperatures touched 79 to 80 C with an overall cpu temperature of about 70 C as shown by everest ultimate under 100% load though the cores idled at around 63 to 65 C.

I use the intel stock cooler.

Are these normal because under factory condition I got those temperatures since I have bought it. Or did i get a defective piece. OR are the softwares inaccurate in showing a proper temperatures.

Probably i gave up the idea to overclock. But still i feel the temperatures are very high. Though after market cooler is a better option...but are these reading normal in a e8400 chip.

Pls suggest.

You need to get an aftermarket cooler. The Tj.Max for those chips are 100. Use reatemp to check out your temps.

You vcore will change if you have C1E and intel speed enabled. Disabled them to get a stable oc. But if I was you get a new cooler if you want to oc that baby.

Yes, Intel released the TJmax for the E8400 and it is indeed 100 C.

Most certainly get an after market cooler, Zalman 9500/9700 is pretty popular. And 99% of OCers will recommend Arctic Silver 5 for your Thermal Paste. If you don't have the money yet for the cooler, At least get yourself some AS5, They sell it at Best Buy. Follow the directions carefully. For instance... Even a finger print on the heat sink surface can affect your results. AS5 should bring ya down several degree's if your using stock gunk.

get the big typhoon. there is an entire section on the forum for modding it to perform better. plus, its very secure, and lays nice and flat on the surface of the cpu.

the only thing i would recommend is lapping the base of the heatsink its not the flattest of surfaces, then again i've owned the zalman 9700 and the arctic freezer and neither of them compare to the big typhoon.

but mostly, check out this thread and it's links:

well they've already told you, but yes you need an aftermarket heatsink.

Xigmatek HDT-S1283 and TRUE are popular.

Lower price ($20-$30)cooler that does ok with temps- Arctic Freezer 7 Pro
Mid Price ($30-50)coolers that perform really well - OCZ Vendetta 2 and Xigmatek S1283
Top end($50+) coolers- Thermalright Ultra Extreme 120 (TRUE)

Those are the ones that i would recommend per price range.

well that was the only suggestions i was xpecting..still ne 1 wid less temperatures on stock cooler....

For the time being, definitely revert your BIOS to remove any overclock. Lower your CPU voltage to 1.25v, and see if Windows boots. If it does, leave it there for now. If it doesn't, keep increase the CPU voltage until it does boot, and then possibly increase it one more notch to be sure of stability.

Then, get an aftermarket CPU cooler. Even at stock speeds, your temps are way too high. The TJMax of your CPU is 100*C. Depending on what the TJMax settings are in your temp-reading apps (Real Temp, Core Temp and Everest), you're likely seeing the wrong temps and they could quite possibly be 5*C higher than what you're being told.

When you remove the stock cooler, make sure to remove the thermal compound with 70%+ Isopropyl Alcohol. Use Arctic Silver 5 when you put the new cooler on, if you're not very knowledgeable on thermal compound. Though there are plenty of viable options out there, AS5 will work fine. The style of cooler you get will determine the style of thermal compound application. For example, if you get a HDT style cooler (Heatpipe Direct Touch) where the heatpipes touch the CPU directly, try this method, it worked well for me.

Also, make sure you have good airflow in your case. Rearrange your cables so they're not blocking the air coming in or going out. Make sure you have adequate intake and exhaust, and put an intake flowing directly towards the CPU cooler, if possible. When you install the new cooler, make sure the CPU fan is blowing towards the exhaust fan in the back.

Hope this helps. Good luck

I'm sure there are some with less temps on the stock cooler. If you don't plan on getting an aftermarket cooler, definitely check out the other tips I posted, including cleaning off the old thermal compound, and using Arctic Silver 5 instead.
