There can't be that big of a difference between CPU temp and Core temp. What are you using for your readings?
Max Operating temp for that processor is 74C. http://www.cpu-world.com/CPUs/Core_2/Intel-Core%202%20Duo%20E7400%20AT80571PH0723M%20-%20AT80571PH0723ML%20%28BX80571E7400%29.html

All those temps are way too high. You obviously have a temp problem if that is correct. Where did you see 40C for core temp? What does Real Temp show for core temp?
Generally, core temp is the sensor embedded in the individual cores. CPU temp can either be the sensor embedded under the CPU heat spreader or the MB socket's sensor. And pgms like speed fan don't specify. That's why I like to read core temp.

Real Temp looks about right for core temps at idle. Maybe a little warm, but nothing to worry about. Probably still got the old thermal paste on, huh? It dries out over time and loses its thermal conductivity. But those temps in speed fan are odd. Whatever it is reading as cpu temp is high. CPU temp cannot be that high if the core temp is only 40C.

1) Remove the existing cooler from the CPU.
2) Use something like isoproyl alcohol to remove the old thermal paste (TIM). Or better yet, pick up this cleaning kit designed for that purpose: http://www.newegg.com/Product/Product.aspx?Item=N82E16835100010
3) Use a lint-free cloth or paper to prevent lint particles from remaining behind. I like to use brown coffee filters. Some folks use lens cloths. Wipe the cooler and CPU surface clean. Be careful not to put too much pressure on the CPU so you don't damage the pins in the socket.
4) Pick up some good quality thermal paste like Arctic Silver 5: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=arctic+silver+5&N=-1&isNodeId=1 ...or MX-4: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007788&IsNodeId=1&Description=mx-4&name=Thermal%20Compound%20%2f%20Grease&isdeptsrh=1 I like MX-4 because it isn't electrically conductive if you get some on the MB.
5) Put a grain of rice-sized dab in the center of the CPU and replace the cooler. The stuff will spread out when the CPU heats up. If you have to remove the cooler for some reason, you should always replace the thermal paste because removing/re-installing the cooler over the old stuff will introduce microscopic air pockets in the surface of the TIM and retard cooling.
You can also get a guide for your particular processor here: http://www.arcticsilver.com/intel_application_method.html#
They recommend the line of TIM as opposed to the dab in the center. But either will work.

thanks for our reply just one more question can you tell if we apply thermal paste more than it needed (assumption) what will happen

Too much TIM will retard cooling. The theory is to put only enough on the surfaces so that when heated and spread out, the thin film fills in the microscopic pores of the metal. With no TIM applied, those pores will form air pockets and thermal conductivity will suffer. With too much applied, there will be a layer of TIM between surfaces, impeding contact.
