Celeron IHS question

[Extol]

What I wanted to know is if I remove the ihs from the cpu is there and heat sinks that will work on there. Thanks

[pappypete]

There are a few people around here that have
removed heat spreaders. Some have also killed
their chip.....If you decide to do so, be careful

Edit...Yes there are HS/F's that will work

[rogue1979]

I just lapped mine, it polished up to a nice copper color, removed about half the material. Running 1430MHz at 1.71v, 38c under full load.

[Extol]

Well then can someone tell me which ones do work I have the sk6 now, and some cheak coolermasters which for some odd reason work better than my sk6. Go figure I get 43c under full load with the coolermaster and 45c with the sk6 and I have lapped the sk6. So if someone could tell me which one works it would be greatly appreciated. Thanks

I'm pretty sure that just about any clip type socket A/370 cooler will work on a Celeron Tualatin with the IHS removed. Just be very careful when you mount the hsf, like you would when mounting it on a T-bird, that you don't chip the core. I've also ,read of several people killing their proc when removing the IHS so think very hard about it before going ahead and doing it. That said, I've heard that the best tool to remove it is a single edged razor blade like you use in a scraper because they are very thin. This is from my reading, not personal experience, so be warned.

[Extol]

Thanks for the advice man.

I was unable to remove mine. Took a lot of force to just get under one corner, became dangerous :(

Any FCPGA compatable heatsink will work, but a shim or something to prop / support some of the weight will be in order since the core is a bit smaller and more fragile than the original coppermines.

[Extol]

Well the reason I was wondering Pinky is because I have a sk6 that I'm getting poor performance with. I get better results with my coolermaster with the delta on it. So I figured if the coolermaster can give me good temps then a good copper hsf should yield better results. Any suggestions

Go here for the temps with the coolermaster after 9 hours of seti@home 1.703ghz (http://community.webshots.com/album/25562246TNHtGnyieo)

[pappypete]

Extol.......that does seem odd. Are you using thermal
compound? (ASII) Also make sure the HS is in good
contact with CPU. I'd use what works best!

[Extol]

Yes I am using ASII, but still a no go the only thing I can figure since it has the IHS on there is it needs a bigger hs to spread the heat evenly I guess, because the coolermaster is somewhat bigger. Any suggestions on HSF.

I heard from some guys that some SK6s don't havevery good connection between the base and the fins... I don't have any first hand experience with this, though...

[pappypete]

Extol....I installed PIII 1.26 S yesterday w/Intel HSF
lapped (ASII) I also found the heat spreader had a
high spot in the center and lapped it flat. My temps,
ambient 22C...idle 26C. You might want to check the
spreader, and be sure it's flat.

Well I think you just hit the nail on the head. Today while I was tinkering around with the sk6 I took it off and looked at the bottom and to my supirse there was only an outline of IHS. It didnt look like the center had even touched it.

[pappypete]

Lapp it......you may be surprised.

[Extol]

Tried that, but maybe I'll give it another go.

[pappypete]

Another possible.....The high speed fans also create
vibration. I have one that I installed rubber "O" rings
between fan and HS, also under screw heads. It
helps with noise and vibration.

[Extol]

Hey thats good thinking. Thanks Pappypete

[Yodums]

Thats odd but I think it should be making contact or else next time use abit more thermal compound.

I think it would as if it wasn't you wouldn't have gotten to 1.7

[Extol]

Is it possible that my sensor isnt reading right, because when I touch the base of it when it's oc'ed to 1703 it is cool to the touch.

[jazztrumpet216]

If you're using that ASUS probe only, those tend to read a bit high. Check it against Sandra or MBM or even your BIOS if it's not a cold reboot.

[Extol]

Sandra says its 29c and the asus probe is right on with the bios. MM5 reports the same as asus probe.

it may be cool to the touch because the heat transfer isn't occurring because of the poor contact being made... are you certain about the IHS being flat now? Taht would made a BIG difference ;)

Mine was flat from the factory fortunately...

[Extol]

Yes I made sure the IHS was flat, but I checked it and again to no avail. I'm starting to think that these tualatins like the bigger hsf like this coolermaster I have. The coolermaster is a little wider than the sk6. What are your temps Pinky with that OCZ Glaciator II.

Consistently 10C above case temps, right now running CPU at 35C full load and case 25C

[Flu!d]

Don't worry too much about the HSF being cool to touch....

Most people forget their body tempreature is about the same as the HSF temperature so it's gonna feel cool to the touch....

[Extol]

Ok, I did some more test. I tried the sk6 with a thin layer of ASII on the IHS and on the HSF same results. Then I tried putting it on thick to the IHS and HSF and results were better, but not equal to the coolermaster. I've tried ASII thick, thin, and even none at all with no difference except for when i applied it thick. Oh and my case temp stays around 23-24 degrees always.

[br0adband]

Ya know, I've read many times around these Forums about Sandra being able to read CPU temps, but never bothered to discover it.

Running Sandra 2002 I just checked it.

Here's the rundown:

The BIOS temps will read 43°C if I just leave it at the hardware monitoring screen for 20-30 mins, so I assume that's stable.

Under Windows XP Pro using Motherboard Monitor and running idle for about 20-30 mins the reading shows 31°C which I'm beginning to seriously doubt. I haven't used the compensation setting since I can't get anything accurate to base it on.

Now I've run Sandra 2002 and it's saying 33°C with a motherboard temp of 31°C.

I know the CPU will always be above the case/mobo temps, so what the hell am I doing wrong? :)

Using AS2 and a cheezy HSF that I'm about to upgrade.

Nothing!?... if I understand your scenerio correctly, which is a bit tough with the way you've layed out the numbers (I have a hard time discerning case/cpu temps)... Looks like your CPU is at 33C and case/motherboard at 31C...

[Extol]

Well I would trust the bios more than sandra. Sandra telles me my cpu temps are 25.9c oc'ed to 1.703ghz. That is entirely false now my bios reads 40c idle and at full load asus probe reads 42c. Post your specs.
