XP-120 Hotter than stock cooler

I have used this cooler in my P180 and I removed the top exhaust because this starves the xp-120 of air. Its stated in a review I read also:http://www.silentpcreview.com/article255-page11.html - they recommend using the back exhaust and letting cool air suck in from the top. The cooler went a good 10'c higher in this configuration.

If I was getting a new cooler I would get the Tuniq Tower unfortunately Ive not seen it for sale anywhere even though it got awesome reviews.

Im pretty sure u will get better temps with the Scythe Ninja though, your exhaust will compliment the orientation of ** cpu fan.
 
I have to say I think it's foolish dropping 40 squid on a new cooler when you haven't discounted the temperature monitor.

Yes it's been said it's showing a difference but that doesn't mean a whole lot.

Right now my bios reports the proc as 60 degrees. Couple of power cycles from now it'll read 20, a few more it'll be back to 60.

I've used a probe and another mobo and I know its more like 35 degrees.

This is just my experience but it sounds like your going to have to nag your dad to use his card so it might be worth just working out if the probe is a factor definitivley.

When your pc has been off for 15 mins and you power on, go straight into the bios, to the temperature monitoring, does it show an instant incline from say 20 degrees or is it just sitting?

Are you able to get your hands on any kind of temperature probe?

How can it be the probe if it consistently reports a stock cooler lower than a xp120. If the probe was dodgy then it wouldnt suddenly change when a new cooler goes in.
 
ive got the XP-120 in now. runnin under and Amber at full rpm. the idle temp is 37-38'c which my old one did but when i load the cpu it goes mental. my stock cooler keeps it at 44'c NO HIGHER than that. but this. i got to 55'c yesterday on full load. :eek: its just not working. its on the mm at the min but no one wants it lol. im not surprised if they have read this... but it'll go on the bay today if no one wants it

XP-120


STOCK AMD

Maybe the air that the CPU fan blows is a factor in what the temp probe reads.

When I went to watercooling 3 years ago, I found that the probe was being cooled by the CPU fan and by going to watercooling there was no airflow around the socket causing (relatively) higher temps.

Maybe the stock cooler blows air over your probe causing it to report lower temps?

but the fan on the XP-120 is much bigger and throws out more air. wouldnt it make more sense that the XP-120 should report lower temps if, what you mentioned was happening?

Not if the 120mm fan is blowing further away from the socket when the stock cooler is ore focused.

But it is a long shot though.

Not if the problem was inconsistant.

Reseating the cpu could be causing the temp probe to reset itself.

I'm not saying it couldn't be the heatsink I'm just saying he should get his own probe in there and work out the temps for himself.
 
Ive decided to lap the heatsink afterall.. going to my dads tomorrow to do it. he has a lot of the wet & dry i need to do it. do you guys have anything that i should watch out for? from personal experience

Make sure you do it on a totally flat surface and not with your hands, makes sure you get a totally even finish :)
 
agreed, Ive read the whole post and lapping the heatsink is worth a shot.

after all this isnt a technical issue we're dealing with here its a lump of inanimate metal thats not perfectly flat and not making a nice contact on the IHS of your proc, its about as simple as that.

p.s. why did previous owner sell? its just about the best heatsink you can buy bar the ninja or tunic so why would he sell unless it wasnt perfoming right either??
 
he sold the processor he was using it with. A64 3500+ OC'd to 2400MHZ and idle'd at 28'c does that sound right to you. is it my system or my ihs thats concaved?

EDIT: is it okay to lap the silver coating off? to reveal the copper one? as seen in the scratch pics?

just realised i didnt put any in the thread lol

well, one would assume that its the bottom of the thermalright thats not level, you could always do the same test as before with the stock cooler, and compare the two for how they contact the IHS.

perhaps a more practical way would be to seat the thermalright and apply some pressure to it manually and see if temps are affected, be careful tho - oh and an assistant would probably be required :)
 
I lapped mine on a mirror so it was flat but the mirror was knackered. I didnt lap my xp-120 much but in the past I have gone as far as a mirror shine on a athlon xp1800 palmino core... ;)

how did those scratches come about, they look fairly substantial, and the fact that they are there suggests that there is a degree of "fouling" on the bottom of that heatsink.

or is that from excessive cleaning ? :)

ed- those peaks really just show that the compound is too thick in that central area and when u pull the thing off its causing that.
 
those scratches came on the heatsink when i got it but they dont actually come into contact with the ihs.

EDIT: im kicking my self now. one time i applied AS5 to the heatsink and the IHS and i booted up converted a film turned off and the As5 in the middle of the heatsink was still as smooth as it was when i applied it. ( it hadnt touched the IHS, the AS5 on both the IHS and the HEatsink base handnt touched in the centre :mad:
