Overheating is the issue of Processor or of Heat Sink

[jerkyshooter]

How can we figure out that overheating is the issue of Processor or issue of Heat Sink?
I'm using i7 4790 with basic air cooler. Its idle temp is about 40 Celsius. When I run Prime 95 on it. Its temp goes to 100 Celsius in just 10 to 15 seconds. Is this problem of processor or problem of heat sink. I mean, is there any problem in Processor which causes heating or just heat sink problem.
Thanks in advance
Waiting for your response.

The spec 4 can handle upto 5 fans. 2x 120mm on top, 2x 120/140 in front and 1x 120mm in rear.

I would set it up as follows.

2x 140mm in front. 2x 120mm top and 1x 120mm in rear. I'd also pair it with a Scythe Fuma Rev.b cpu cooler. That'll all come in under budget. You won't find a decent 240mm cooler for that price range unless it's used or really unpopular for a reason.

The Scythe Fuma Rev.b is a 149mm tall, twin tower cooler that's almost as good as a 160mm Noctua NH-D15S but will fit inside your 150mm case requirements easily as they are wrong, you have about 159mm of clearance. The Fuma at @$50 is by far one of the smallest footprint, most able coolers at anything close to that price, considerably better than the 145mm cryorig H7 or the 160mm CM hyper212 evo. It's also very quiet. It's ability, coupled with normal usage will mean it'll also be almost dead silent until pushed hard and being a 250w+ tower will mean it'll handle anything that i7 can dish out easily.
