2.26 P4 = 51 C

[jellognome]

I have a 2.26 P4 @ 2.72 on an ABIT IT7 Max and I'm running VCore at 1.7v.

I have a Swiftech MCX478 and thermaltake smart fan.

Why is it so hot? This is with the case open so intake and exhaust fans aren't the problem. Loaded temps are about 60C.

I'm thinking of watercooling so it's a little more quiet, and maybe even a peltier.

Also, it seems a lot of 2.26's are able to reach 3 GHz. What boards are people using for this and what are the temps? Should I try and go higher on my 2.26 or leave it as it is until I get better cooling?

[dansonang]

looks hot but not hot enough to kill yr processor.

I bet the problem lies in that smart fan. it does not cool yr cpu well. get a vantec tornado

[JaY_III]

your temps are VERY higher for that HSF combo.....
are you sure you have the heatsink seated correctly?
I would unmount and remount the heatsink.

Also, what type of thermal paste are you using?
as using low quality stuff (such as the pad if bubble gum that comes on mist heatsinks) can really hurt temps.

and how are your case fans setup? intake in the front, exhaust in the rear?????

and by any chance do you know what your case temp is, or even your room temp?

[dansonang]

bubble gum on heatsinks??

then its time to lodge a complain to the HSF makers. artic silver 3 is a good thermal compound for reducing temperatures

Yeah, bubble gum, the square pad that looks like bubble gum and cools just about the same....
thats what i call the thermal pad that most sinks ship with.

the heatsink looks like it's seated properly (flat from all angles). I used arctic silver 3 when I put it on. I could try reseating it if that is the problem. I'm trying to figure out what I did wrong when seating it. I'm thinking
1.) too much as3
2.) too little as3
3.) heat sink on too tight
4.) heat sink on too loose

do any of those sound right?

What kind of temps should I be hitting with this hsf combo?

edit

oh, about the case. It's a lian li pc 65b. There are two intake fans and one exhaust fan. But when I put the side of the case on the temp goes up like 8 degrees, so I'm leaving it off for now. system temp is usually between 36 and 38 C. Ambient temps, I haven't measured, but are most likely 70-75 F.

[jellognome]

okay I'm running Folding@home now and the temp of the CPU is currently 60-61 C, System Temp is 40C. The heatsink feels warm and the metal plate of the heatsink that is touching the heat spreader on the processor is hot. So is the problem still with the heatsink? I want to refit it but I don't want to refit it the wrong way. And the heatsink feels warm evenly on all sides if that helps at all.

[masitti]

You wanna put a nice, even, thin layer of AS3 on. It should be kinda transparent, about 1 piece paper thin. Your temps do seem high; make sure that any pad that was on the heatsink is taken off, and the h/s is cleaned off too.

[jellognome]

What I did was I put the AS3 on the heatsink, rubbed in circles with my finger using a plastic bag (I used 91% alcohol on the bag and then heatsink first). Then I wiped the AS3 off the heatsink completely, put some AS3 on the CPU heat spreader and rubbed in circles with bag again. Then I attached. Is this wrong? This is what the instructions said to do. Do you have to smooth the AS3 when you are applying it?

[Ben721]

Artic Silver is awesome.

[yoink]

the heatsink being hot is usually a sign that it it working. I would be wondering about the fan on top of it. That could be the culprit. I think the HS being hot really clears it of any wrongdoing! After all, thats what heatsinks do, they transefer heat!:D

[dansonang]

I don't really feel adding too much as3 can kill (not so much that when u put the hsf on it, as overflows)

I think too little as3 kills

[dRagOOn101]

my temps are about 38C idle, 48-50C load... that's at default speeds w/o vcore bumping... but even when i was running the intel stock hsf, the temps were only marginally higher..

your difference in temp range may just be a result of different motherboard manufacturers using different temp sensor chips, etc... someone once said on here that Asus boards tend to inaccurately give off lower temps.. maybe abit's the opposite..

i would say, don't worr about it unless you see a problem with your system or it cuts your ability to overclock.

Thermal paste is supposed to fill in the little tiny microscopic holes, dents, etc. that can be found on your heatsink.

If you put to much on, it IS an overkill; you want a very thin layer of it on. If not, than that defeats the purpose of what it is supposed to do. :)

[jellognome]

well it's certainly not the fans, right now I'm pointing a 12 inch fan directly at the heatsink and while the system temp has gone down 4-6 degrees Celsius, the CPU temp remains at 50C. So I think it is a problem with the way I have attached the heatsink or the way I put the AS3 on, I still am unsure if it is

[Scottland]

if i had to guess your problem is two things....one your system temp is high 40C ( thats 104F) inside your case

air cooling theoreticly can only get your processor down the the ambeint temperature. so if you have high ambeint it hurts

the #2 thing is that smart fan. ditch it and us it for additional case cooling and for the swifty get a big fat Delta 80mm screamer or a Vantec tornado or something....

the cheapest fix looks like trying to bring those case temps down... take the side of the computer off maybe get a box fan to blow in the side or something... if you can bring hte case temps down your heatsink won't have to work nearly as hard

[masitti]

Yea that would be a good idea, put like a house fan (like 10 to 20 inches) blowing right into the case, and see what the temps do.

[jellognome]

Okay, well I did try with the house fan blowing directly into the CPU and I had temps of 50C still. The case temp went down 8 degrees, but the CPU temp did not change.

Now I have recently just reattached the heatsink THREE times, each time wiping off both the CPU and heatsink with 91% isopropyl alcohol and then reapplying arctic silver 3. I have tried twisting the screws as tight as possible in affixing the heatsink to the motherboard, and I have tried without any screws at all. I have tried with the fan blowing towards the CPU, and I have tried with the fan blowing away from the CPU. The temperatures in every situation are still around 50 C for the CPU temperature.

When I looked at the heatsink, there was an imprint of the CPU core on it. and yes, I do mean the CPU core, about 1 cm by 1 cm in the center of the outline of the processor. It didn't have the faded color that the arctic silver 3 leaves. Is this normal? I'm beginning to think that the problem lies with the heatsink, that it is a faulty heatsink and the actual metal isn't flat. it certainly doesn't give a mirror-like reflection if heatsinks are supposed to. I certainly can't make out the shape of my head when I look into it. Is it suppsoed to be as reflective as the back of a CD?

This is really frustrating me, I don't know where the problem is and it could be anywhere. An elevated bump in either the processor or heatsink, or the motherboard is reading the temperatures wrong.

I have connected the smart fan to the CPU header on the motherboard and I can't read the RPMs in the bios or in MBM 5 or in any program that reads RPMs. To any other IT7 users, can you read the RPMs?

I'm about to throw this damn thing out the window... I should also mention that the yellow digital POST code has been broken since the day I bought it. It worked for about 30 minutes and then never worked again.

Someone else on these boards has a 2.26, mcx478, and an abit it7 (exact same setup as me) and has temps of 40 C for the CPU, overclocked to 2.82 I think.

By the way, you all have been extremely helpful so far and I'd like to thank you.

[Sleepyhead]

Personally I suspect that the problem is *not* the HSF combo or how it is fitted. My guess is that like me your IT7 is reporting sky high temps.
My specs are:
Lian-li PC61
2 42CFM YS-Techs intake (no filter)
3 30CFM YS-Techs exhaust
2 PSU fans (no idea on CFM, but its a 350W Enermax)

P4 2.26b @ 2.72 - 1.55v actual
Room ambient temp: 22c

System idle temp: 32c
System load temp: 40c

CPU idle: 49c
CPU load (Prime95): 65c

HSF feels pretty warm, but not 65c hot!

Have a look at this thread here about the IT7's bizarre temp reporting:

[dieselstation]

i think the fault lies in the Abit board's temp sensor. My Abit BD7II reads 43idle and 56load.. but when i touch the heatsink.. it's NO WAY it's at 56. it's not even warm like my old XP2000+ which was also at 56C load. i think the Abit may be off by as much as 10 degrees!

[dansonang]

maybe u r right. but to me it is wrong

i added more as3 than usual and i got mcuh better results

[jellognome]

Well I changed Sensor 2 to WinBond 2 2N3904 in Motherboard Monitor, I set my VCore to 1.65 (1.58 actual) and VMem to 3.2 (2.96 actual). 2.26 @ 2.82, CPU temp is 34C loaded:eek: ! It seems too good to be true for my MCX478. But hey at least it's not 54 like it was before:burn:...!

By the way is VMem 2.96 too high? I'm on some DDR 400 Corsair XMS, it's great.

I don't think the system temp is right because it's reading 37C. Upon blowing a house fan into it, it will go down significantly but I think it is not calibrated correctly. I think the System temps are calibrated too high and CPU temps are calibrated too low.

[dRagOOn101]

if you got your load temp down to 50C, i don't think there's anything to worry about... my system hovers in that range of temps during load.. and it was around 52-53C with the stock Intel HSF... so if you're trying to get your temps down to "normal" temps, you've suceeded..


but I still stand by my previous hypothesis.. which is that the temps are probably incorrect/differerent only because the motherboard manufacturer uses a different temp sensor than others... the only way to really tell is to pick up your own temp sensor and judge it yourself w/o the aid of the mb's built-in sensor.
