is this a good combo

At the moment im running a 3200xp with its standard cooler
thinking of putting a 80mm Vantec Stealth with a Thermalright SLK800-U
would the stealth be powerful enough ,trying to keep my system quiet as poss.
Any feedback would be welcome

 

I would say that'd work, it depends on the rest of your case setup of course - are you keeping it in a sealed box or do you not have a case at all? Case cooling makes a lot of difference.

(Hope the SLK800 can cope with yours, i've just acquired one for my rig...)

 

does the slk800 take a 92mm fan, the 92mm stealths are a fair bit better than the 80mm's, if not i'd suggest going for the slk 900

 

no, it does not.

 

my case is sealed got a 120mm intake at the front and a 120mm outake at the back, i know this should be enough but my core temp is close on 70.And im not happy with that.

 

then it may not be seated properly, what are your case temps?

 

My case temp normally sits around the mid 30s , you can see my concern about core temps

And with summer just around the corner things can only get worse.
Begining to think that there could be a problem with the seating of the heatsink , as my Gfx gets no higher than 57 under load

 

reseat it, i'm presuming you pulled the plastic tag off the thermal pad, but lefft the pad on as you should?

 

consider removing the thermal pad (making sure not the scratch the heatsink) and clean up the bottom of the heatsink with 96% pure (or better) alcohol, then apply a VERY thin layer of good quality thermal paste to the core and re-seat the HSF.

i replaced the thermal pad for some as5 on the family's P4. also cleared a little dust, and cleaned up the wiring. temps dropped close to 10*c
