cpu replacment

[jkresh]

Currently running a p4b533-e with a 2.26 at 2.6, have been running that for 1.5 years without problems but recently my system has been crashing and cpu temps have gone up quite a bit (from 40C load to 49C load), without any other changes so I am guessing that the proc may be in trouble. What would be the best chip to replace it with (price performance) that would work in this mobo (i845), don?t want to replace the motherboard till pci express is here. Any suggestions would be appreciated.

dust out you system
prob loads of dust after 1.5 years

get a compressor or a can of compressed air

I recommend, if you are scared of doing it, removing your heatsink and removing the fan from it. Clean the heatsink fan itself really good with some strong spray soap (I use something called Mean Green that's available at Dollar General for $2 for a 32 oz. spray bottle) or at least Windex, and Q-tips. Just hold the Q-tip against where the spray comes out, and get it wet, then you can remove quite a bit of crap with each Q-tip. Clean every fan in your case completely (both sides of each fan blade). Now, take your heatsink and if you have a sprayer, using only hot water, spray it until it's completely clean, then let it dry completely. Alternatively, after cleaning your fans, you can use a $5 can of compressed air to blow out all the dust from your heatsink, then use any of the air that's left to blow the dust out of your northbridge heatsink, and off of your video card, sound card, etc. In an hour or two, you can have loads temps of 40C again for another year or year and a half, if you don't mind pressing your luck.

Might try full cleaning, but clean every month or so with compressed air/small vacuum, and antistatic dust cloth, also clean filters on intake fans, so it is not likely to be a dust issue, may be time to replace the thermal paste on the processor though. Thanks for the suggestions. Also, motherboard temp has not changed, while processor has gone up 10C so it doesn?t appear to be a casewide airflow issue.

You may want to reapply Thermal compound, since it has been 1.5 years. If it has a thermal pad scrape it off. I used a credit card to get it off, Thus not scratching the HS. Use high purity alcohol to clean HS and core with. Use a lint free towel or lens cleaning cloth to absorb the alcohol and wipe off any excess.

I too would recommend cleaning out your old heatsink/fan. Look at mine before I cleaned it out! yuck LOL

As far as an overclockable cpu for the Intel 845 chipset I would say go for a P4-3.06 like I did. I've only had my for a week and a half and just started overclocking it a couple days ago. I am on an Abit BH7 which uses the 845 chipset and only supports up to 533fsb in a stock mode. It runs 800fsb P4's but it would be considered overclocked. I have recently been running this cpu at 140 which x4 equals only a 560fsb. This gets me up to 3.23Ghz with no voltage bump and no added heat that I can see. Prime95 torture test stable for 5hr15minutes last night until I woke up and turned it off. Voltage never went over 1.5 either(BH7 tends to undervolt the cpu and the normal voltage for this cpu is 1.55v). Prime95 got the cpu up to 122F in my rather warm room.

I would start with cleaning out the old heatsink and then consider this cpu. HyperThreading kicks butt and so does 3Ghz+ speeds!
