Hi people !

First of all im sorry if this is posted in a wrong section...

Well right now im gettin problems with my CPU temperatures..

They rise to 70-75 Celsius when playing games, and 50-60 while in Stand-By.

Here are my system Specs:

AMD Athlon 64 X2 5200+
MCP61PM-HM (Nettle3)
3GB DDR2 RAM
ECS Nvidia GeForce 9800 GT Green Edition 1GB DDR3
Integrated Realtek ALC888S Audio
500 GB SATA 7200 rpm
CoolerMaster eXtreme Power Plus 600W

This is my PC before i bought the GPU and PSU :P

My pc is about 3 years old now and i need to know if i should go to the technician :P

Thx for your help !

Your spec's show only one case fan is that correct. Tell us what you have for cooling. Also what case do you have.

When was the last time you popped it open and cleaned out the dust bunnies? If it has been a while you may find that the heatsinks on the CPU and video card are clogged, which can and will lead to higher temperatures. If you have never done that sort of thing here is a fairly good how-to,

About the only thing I would suggest that he didn't do is to stick a pencil or something in the fan to stop it from spinning when blowing on it with the air as it can damage the fan from the excessive RPM's.

If you haven't done that sort of thing before or you're uncomfortable doing it yourself, then by all means take it in to be done. Be advised though it will cost quite a bit more than the $10 or less a can of air can be bought for.

Good call stormy13. I noticed the video card has been changed from a GT-6150 to GT-9800 and the power supply too. The reason I asked about the fans is how many and are they working. Their are many things that can cause cpu to over heat so I start at the basics.
1. As stormy stated, clean everything.
2. Are the fans working and how many do you have.
3. Have you change anything and how long ago before this problem started.
The GT-9800 creates a lot of heat that must be remove from the case or every thing gets hotter.
Your GPU will run that hot 70 to 80c when humping them gaming but your CPU should not.
When we know these things are correct we can get deeper into the problem.
Please get back to us.

Your CPU max temp is 74°C, so you are operating at a dangerous level, this needs to be fixed before you damage the CPU.

After following all of the good recommendations above, if your temps aren't down to 30°C when at an idle, you may need to check you CPU-cooler thermal paste.
This has to be put on correctly or the temps may get worse, so you might consider taking it to a technician as you mentioned.

Best plan is to give it a thorough cleaning first, then check CPU temps again.

Hi guys !

Thanks for the quick replies.

Well i ve got only 1 small fan cooler in the back of the Case ( THIS CASE HP Pavilion a6532f Desktop PC Product Specifications HP Pavilion a6532f Desktop PC - HP Customer Care (United States - English) )

Only 1 Fan (default random fan) pulling out hot air, and the CPU/GPU default coolers.

Here are my GPU specs :

I cleaned the CPU and motherboard like 2 times this past 3 months lol.

I noticed the problems after installing both the GPU and PSU.. Maybe i should change the thermal paste since almost 3 years have passed.. or install some addicional fan cases..

Hi Chronox

If you can install another fan in the front of the case to push air in, that will be of great help.
If you know how to replace the thermal paste between the cpu and heatsink, i would say, give it a go.
If you haven't tried it, here is a good guide to get you started.
The original thermal paste on new computers is not always the best. I have seen some shockers, before i started building them myself.
When you have the heatsink off, that would be a perfect time to give it a really good clean too.
As they say, "every bit helps".

spinifex nice idea, but with that HP case an extra fan i the front just isn't going to happen. This is what that model looks like on the inside,

You get down to it there isn't a whole lot of room for much of anything. It also doesn't help that HP insists on using inverted ATX cases with what looks like little to no thought for cooling. Then again they would rather sell you a new computer than allow you to upgrade anything in an older one, so why make it easy.

I noticed the problems after installing both the GPU and PSU

With how little room there is, good possibility. I assume this is the PSU you got,

Newegg.com - COOLER MASTER eXtreme Power RS600-PCARE3-US 600W ATX12V V2.3 SLI Ready CrossFire Ready Power Supply

If not it doesn't matter much as they will all be basically the same with regards to the fan in them. When you put it in the case did you put it in with the fan facing down, or facing up into the top of the case? Ideally it should be facing down to help with pulling warm air out. Looking at the service manual for it it should be facing down as ATX power supplies normal only mount one way (the 4 mounting holes are the same on all ATX cases and power supplies).

If it is facing down there is also the small problem of where it is in relation to the video card, which due to the case has its fan facing up where in a normal case it is facing the down. This will case the two fans (PSU and video card) to fight each other, as the fan on the video card is pulling air in from the same small space that the PSU fan is. Unfortunately unless someone else has a better idea, if that is what is happening the only way I can really see to fix it is another case.

I have modified this case by putting the hard drive in the 3.5 bay and removing the HD bracket and putting as big a fan as will fit in the front of the case. Might work in that case or not the ones i have modded were a little different.

Okay we have got down to how many fans and do they work. I think that was note 2. in my previous posts. One fan is not going to get the job done. (PERIOD). If you can't figure out a way of installing more case fans you need another case. Tell us how much money you have to spend on a case and we will help you pick one. Remember step at a time. Power supply, you got that covered. Step 2 a case that will cool. I don't care what it looks like, does it cool? Step at a time and we will get you there.
