Athlon 64 IHS

Thats not the problem for me, I'm on a Zalman 7000cu

*scratches head* Haven't seen that one, but ok

 

[Ketxxx]

yeah, right now my pc is laying on its side lol, really have to figure out what needs to be done as nobody has covered it before (yes i know i could look at my hsf and figure it out in 5 mins flat, but im lazy) interestingly, i still cant be bothered to fit my VF900, but i was bothered to tske my IHS off lol

 

[CjStaal]

lol
So is the hsf base smaller than the socket?q

Yep.

 

[Ketxxx]

Yep indeed it is, anyone come up with anything? my googling hasnt turned up anything that useful yet.

i aint read it but it has plenty of posts..

looks like im gonna have to mod my retention clip, i would also advise getting some rubber pads, although an A64 core isnt nowhere near as fragile as ppl say, it is more than the old XPs.

 

[CjStaal]

Really? Hmmm might do it...
I get 39c on water cooling...

4 layers of electrical tape make a nice pad, and also protects the small chips around the core. Might experiment a bit though to make sure its getting good contact though.

Modded and done, got some custom little foam pads all cut up, stuck them with the smallest dip of superglue, then bent the retention clip so it was as "flat" as possible, moved it up one bar on the Zalman, andnow it fits like a dream (actually, it fits better than it ever has) idle temps for me now are about 30c @ 1.42v.

What were your Idle temps before?

Also did you compare load temps?

 

[Ketxxx]

Not compared new load temps but idle temps before @ 1.42v were about 37c. termal compound was also applied perfectly, temps just never got lower than 37c. But now their between 28-30c, which is just awesome, next will be seeing how much further I can OC, fingers crossed for 2.7

So about 8c idle temps, I'd like to see the load temps.

I bet at least a 4c temp drop, which is pretty darn good.

 

[Ketxxx]

I hope more than 4c as its load temps that were always much higher than they should of been (well in their 50s+) so I'm hoping for a max load temp of like 48c.

 

[wazzledoozle]

I idle at 30 celsius @ 2.4 ghz... if I take the IHS off and my temps drop 10 celsius ill be at room temp

 

[Ketxxx]

My CPU actually idles below ambient temp, which just rocks

 

[bigboi86]

How is that physically possible though?

 

[Ketxxx]

Ambient = system temp
Quite easy for a CPU to idle below that, all it takes is a good cooler and thermal compund, with the removal of the IHS

 

[trog100]

course it cant idle below ambient.. only in your imagination.. it aint magic.. ambient being room not system temp..

trog

 

[Satchmo]

im sorry doesnt ambient mean.........surrounding, the area around or encircling?

unless your mobo is designed to read temps from another diode possibly the northbridge or something and uses the ambient temp display feature for that diode.

theoreticaly, if you could cool your cpu to 0c, and you put your finger on the ambient sensor diode, your cpu would be much less warmer then your ambient.

A cpu cant be colder than the temperature of the air in the room blowing over it, unless you have something like a waterchiller or a phase change system. In cases where it seems people are idling at below room temp, it is because their thermal diodes arent reporting the temperature correctly.

 

[W1zzard]

yep mobo sensors can be WAY off .. i've seen everything between -15°C and +17°C.

you cant compare temperatures between rigs. they are valid only for your individual mobo/cpu combination.

 

[Ketxxx]

my bad i meant mainboard temp, see children? that is why you shouldnt post late at night when your tired.

 

[infrared]

It doesn't matter what component your getting that temperature from... It's physically impossible to have a temperature lower than ambient

Even with watercooling, unless you are using chilled water, it's impossible to go below ambient, because the water can only be as cool as the air going through the radiator.
