Overheating Issues? I'm not sure...

[Kirin]

Finally got my PC working from my previous thread:

2.8 Intel Core 2 Duo
Asus P5Qc Motherboard
Sapphire Radeon HD 4850
2x2 gig DDR2 1066 GSkill Ram
520w Corsair Power Supply

My problem now is that the pc probe program that came with the asus mobo, as well as speedfan and cpuid monitor are giving me temp readings that seem hotter that what ive become accustomed to with the case im using. But these are new parts, so im not really familiar with normal temp limits for them.

They run at these temps:

Idle: CPU 30-33C
Mobo 35-38

FFXI, Opera, and VLC running: CPU 52-65C
Mobo 48-50

Alarms go off for PC Probe when i start putting stuff on under load. In terms of cooling, stock fans are on the CPU and GPU, 1x80mm case fan blowing intake on the CPU, 1x120mm exhaust fan on the back, and another 80mm exhaust fan at the top of the case. I've fiddled with adding more intake fans to the front of the case, but that doesnt seem to help. There are no more case fan slots on the case, just those 5. (4x 80mm, 1x 120mm) I think hot air from the GPU might be getting trapped down at the bottom of the case with nowhere to circulate, and is upping the general temp of the case as the hot air rises.

I understand higher yield parts = more heat = need more cooling, but I havnt had problems through 3 days of 100% operation. Only thing I can think left to do is look into a new case. Or am I just worrying for nothing and those temps are fine?

I appreciate the comments. This is a huge learning experience for me building a unit on my own and i've learned a lot from previous help!

65 degrees seems pretty hot if it's not under full load and not overclocked. It's within guidelines, but could be lowered.

Make sure your fans are blowing the right direction. Clean up your wiring to help airflow.

You can also remove the CPU heatsink and redo the thermal paste as too much, too little, or poor spreading can really push temps up. The stock Intel coolers come with some already applied, but I'm not sure how effective it is. Someone else may know.

Aside from the stock cooler not really being that great, thermal paste needs to be redone each time you detach the cooler. In the case of the stock cooler it has dried paste pads from the factory so you'll need to remove it with the flat edge of a razor or some shit.

Your idle temps seem fine, don't know why it rises to 65 under load however. Reapply the thermal paste and get a good off brand one like Arctic cooler.

I actually had a friend apply the thermal paste whose done it 100 times before, but to have him do it would require an hour or so drive.

Is it difficult to reapply the paste? And if im doing it should i go ahead and replace the stock fan on at least the cpu as well with a more efficient and cooler heatsink?

The hardest part is usually removing the heatsink from the chip without pulling it out of the socket.

Nah it's not difficult at all. In fact the hardest part I've learned is trying to remove paste that's still fairly new, but even that's not so bad with a whole buncha q-tips and 97% isopropyl alcohol.
