My cpu is 44C when i have great cooling ( i think )

these are my temps



i have

p180b antec case
2gb coursair 6400
p5b duluxe mobo
e6400 with a zalman hsf

i was wondering what should i do to get the temps lower because this is horrible. I haven't even overclocked my computer yet. I have not did the 100% tests on the cpu so thats basically temps on idle - 10% load on e6400 ( which is 5% on each cpu )

  1. dt, it is not possible to advise you without complete information. Please test your system, then post the results and variables as shown in the Core 2 Duo Temperature Guide.

    Hope this helps,

  2. yeah.. it is hot.

    tjunction - 85C

    core 1 - 52

    core 2 - 51

    No.. it is not.

    dt, Core Temp's "Tjunction 85c" field is merely a display of Intel's Tj max specification (shutdown temp), which is information only, is not an active temperature reading, and is not intended to change. Once again, please provide complete information, as shown in the Guide twice:

    Background

    ...when expressing Idle & Load test results, it's also necessary to define the variables such as:

    Tcase = Idle & Load
    Tjunction = Idle & Load, Hottest Core

    Ambient = Room Temp
    Chipset = Model
    C2D = Model
    CPU Cooler = Model
    Frequency = CPU Clock
    Load = Test Program
    Motherboard = Model
    Vcore = CPU Voltage

    Results

    Tcase (Motherboard Utilities) = 30c Idle, 50c Load (SpeedFan: CPU or Temp X)
    Tjunction (TAT) Hottest Core = 45c Idle, 65c Load (SpeedFan: Core 0 / Core 1)

    Variables

    Ambient = 22c
    Chipset = 975X
    C2D = E6600
    CPU Cooler= AC Freezer 7 Pro
    Frequency = 3.6 Ghz
    Load = TAT @ 100% 10 minutes
    Motherboard = Asus P5W DH
    Vcore = 1.45

  4. i was going to ask for his voltage.

    But you forget when you bump the voltage on these C2D chips from stock to 1.4V your TDP went from 65W -> 121W something you guys should concider.

    That means the heat output generated has nearly doubled.


    Dont compare your temps with people on medium/high end water even with a tuniq. You'll lose badly, expecially since water has a bigger edge at higher temps above ambient.
  5. aigomorla, Speedfan 4.32 reports his VCore as 1.30V and he said he hasn't even overclocked the system yet. Definitely there is something else going on here. Core Temps reports he's running his E6400 at stock speed 2.13GHz on the Zalman HSF (which one? even with a worst Zalman 7700 Al it can not be that high).
    dt, are you sure you have the Zalman HSF seated right? I'd remove the Zalman and take a closer look around one more time. You don't get those temps in idle at stock speed, not even with the Intel HSF. Didn't you forget to apply some AS5 on the heat sink? Just asking, I don't think you have. Leave the case open with the sytem running and watch the temps after 15-20 minutes. How are the temps then?
  6. I'd suggest checking the thermal compound and reseating the hsf as well. Also, I was wondering if you'd tried turning the fan speed regulation off in the bios - and if your zalman has the fan regulator that comes with 9700 - try not to use that. ie. make sure it's running full speed.

    okey i completely missed his voltage on speedfan. I figured it would be another typical high oc thread. I appologize. Now i have 2 theorys.

    It seems you got there a B revsion CPU according to CoreTemp. These off bat run a little hotter then normal C2D chips. if you google it, you'll get tons of hits.

    Now another issue is you have a E6400. Im guessing thats a fairly old E6300. Dont get me wrong, the B revsion is an awesome chip, so you got yourself a nice ocer. Anyhow, b4 i drift off, the old E6300/6400 had absolutely horrible non flat IHS. On anandtech we would get ~3-4 posts per day reporting this issue.

    Now the easiest way to see how non flat, or how flat your cpu is, take a razor and put the edge against the top. Any visible light means your IHS is not flat. You now have 2 choices if your IHS isnt flat.

    1. you can submit an RMA to intel. <would be a waste of a good B revision chip tho>
    2. you can lap your IHS to make it flat. Im figuring you ran all your rest, and its just a heat issue your machine is unstable.


    You should becareful about option 2. You will void your warrenty. But then again, you already voided it by not using the stock hsf as per intels warrenty guidlines.
  8. I thought you were going to leave this forum after the water cooling incident earlier?

    yeah... but who is gonna tell intel that when they are going to rma something? not me.


    this is how my computer temps look when i just booted it up as played around for about 20 mins.

    what does the W suppose to be on my e6400?
  10. .....er yeah...these kinda posts...
    44C that is by no means hot.

    core2duos overclock quite a bit without a vcore increase, so we can say the stock voltage is high.
    If you are that worried lower your voltage. That will lower the temps.
  11. This is morning temperatures. My ambient at night is = 32C to 34C with fan on ( my ceiling fan :) )

    Ambient = 23C

    Vcore = 1.30
    C1E / EIST = Disabled
    CPU Fan = Manual, 100%
    Computer Case Fans = Manual 100%
    Primary Test = TAT @ 100% 10 Minutes

    Tcase (SpeedFan: CPU) = 38c Idle, 52c Load

    im in the middle of helping 3 people on this forum. After they've completed there stuff, i am leaving.

    Honestly, it seems this forum is too overloaded with koolance junkies, and other people who live on giving wrong advice.

    This i just annoys me. So instead of insiting flames in my theads, i decided to go back to my home forums, where my knowledge is more apreciated.

    And yes on that forum i did pwn that fool who started to flame me. And im sure that op is going WTF have i lost after linking him those 2 last posts that totally show i was correct.

    Anyhow op, i highly suggest you try that razor technique i explained. It worked wel on anandtech, and also cleared a lot of non flat ihs questions. Im highly leaning twords you not having a flat ihs if your getting those temps at a stock setting with a cps9500. your idles should be in the mid 20's and loads near or at 40's if i remember correctly.

    i just cleaned my e6400 and the fan with some alcohol and placed some of my as4 on it and its lowered about 2 -4 c. I guess the first time I didnt add enough or something.

    Now, 38C idle and 52C load temps look much much better than previously 52C idle (and may be 70+C load?) And that's 14C difference, not 2-4C. I guess you made some mistakes the first time, eh? Everybody does from time to time. Anyway, congrats to you, dt. Cooling problem resolved.
  16. I have a miniR/120 water cooling system for my cpu and it still runs at 43c-46c when under load.No worries about that temp on air.

    i overclocked my cpu and now i get 52 c idle and 71c load @ 3.20 ghz on e6400 c2d. the cpu ( speed fan ) stays at 35c

    regular temps without being overclocked is 38c and 52ish load. problem is fixed but i wish i could do better with that cooling. the cpu ( speedfan) stays at 44c
  18. I thought I had heat issues so I decided to lap both my E4300 and my Scythe Ninja. Turned out my heat issue was a non issue. But thats another story. Although I really didnt need to Im glad I did. Both my CPU and my heatsink looked like this:

    After lapping to a mere 600grit(3 stages. 200, 400, and 600) and using ceramique I dropped like 8C.

    wow, you got skills. i have no idea what that all means but i do see the picutre and the hs is not even at all.

    lapping means : "shaving" some of the heat sink stuff off and recoating it with the copper on it and placing it back on the cpu for cooler temps?
